Introduction
The Power Xpertt 9395 uninterruptible power supply (UPS) is a true online,
continuous-duty, transformerless, double-conversion, solid-state, three-phase system,
providing conditioned and uninterruptible AC power to protect the customer's load
from power failures.
The Power Xpert 9395 Three UPM UPS (650–825 kVA) contains two sections: a
section configured either as an integrated system bypass module (ISBM) or an Input
Output Module (IOM) rated for a maximum of 825 kVA and an Uninterruptible Power
Module (UPM) section containing three UPMs. Each UPM is rated for a maximum of
275 kVA for a total maximum of 825 kVA.
The UPS Plus 1 model (650–825 kVA) using the Field Installed UPM (FI-UPM)
provides N+1 redundancy for the system (see paragraph 1.2.1).
The Power Xpert 9395-825/550 Two UPM UPS (450–550 kVA) contains two sections:
an ISBM or an IOM rated for a maximum of 825 kVA (to provide future upgradability)
and an UPM section containing two UPMs. Each UPM is rated for a maximum of 275
kVA for a total maximum of 550 kVA. The FI-UPM is not supplied as standard, but is
available as an option to provide upgradeability to a maximum of 825 kVA. Adding the
FI-UPM can also provide N+1 redundancy if the power requirements are less than the
two UPM rating.
The UPS is available as a single unit or as an optional multiple unit distributed bypass
system (see paragraph 1.2.5).
The Power Xpert 9395 online power protection system is used to prevent loss of
valuable electronic information, minimize equipment downtime, and minimize the
adverse effect on production equipment due to unexpected power problems.
The Power Xpert 9395 UPS continually monitors incoming electrical power and
removes the surges, spikes, sags, and other irregularities that are inherent in
commercial utility power. Working with a building's electrical system, the UPS
system supplies clean, consistent power that sensitive electronic equipment requires
for reliable operation. During brownouts, blackouts, and other power interruptions,
batteries provide emergency power to safeguard operation.
The UPS is housed in a free‐standing cabinet, divided into two sections to facilitate
shipping. The sections match in style and color and have safety shields behind the
door and front panels for hazardous voltage protection. The FI-UPM matches the UPS
in style and color. Figure 1‐1 shows the Power Xpert 9395 Three UPM UPS
(650–825 kVA). Figure 1‐2 shows the Power Xpert 9395 Plus 1 UPS (650–825 kVA)
UPS with the FI-UPM. Figure 1‐3 shows the Power Xpert 9395-825/550 Two UPM
UPS (450–550 kVA). Figure 1‐4 shows the Power Xpert 9395-825/550 Two UPM UPS
with the Field Installed UPM (450–825 kVA).
NOTE Startup and operational checks must be performed by an authorized Eaton Customer Service
Engineer, or the warranty terms specified on page W-1 become void. This service is offered as part of the
sales contract for the UPS. Contact an Eaton service representative in advance (usually a two-week notice is
required) to reserve a preferred startup date.

Installation Features
Each UPS section is shipped separately. The sections are mechanically and electrically
joined at the installation site, and can be permanently bolted to the floor.
Power wiring can be routed through the top or bottom of the cabinet with
connections made to easily accessible terminals. Control wiring is routed through the
top of the cabinet and must be installed in accordance with Class 1 wiring methods.
1.1.2
Control Panel
The control panel, located on the front of the UPS, can contain a liquid crystal display
(LCD) and pushbutton switches or a 10-inch color touchscreen to control the
operation of the UPS and to display the status of the UPS system. See Chapter 7,
“UPS Operating Instructions,” for additional information.
1.1.3
Customer Interface
S Building Alarm Monitoring – Up to five inputs in the UPS are available to connect the
facility's alarm system contacts. Some system configurations may limit the
number of inputs available. The UPS uses these inputs to monitor the building
alarms in addition to the UPS status. See Chapter 8, “Communication,” for
additional information.
S Alarm Contact – One alarm contact is provided for connection to equipment at the
facility, such as a light, an audible alarm, or a computer terminal. The equipment
connected to this contact alerts you to a UPS alarm. See Chapter 8,
“Communication,” for additional information.

INTRODUCTION
1.2
Options and Accessories
Contact an Eaton sales representative for information about the following options.
1.2.1
Field Installed UPM
A Field Installed UPM (FI-UPM) provides upgradability for the Power Xpert 9395
825/550 two UPM UPS. The FI-UPM may be installed at any time in the future when
power needs change. The module cabinet is installed on the left side of the ISBM
section and is wired directly to the UPS. No input or output wiring changes are
needed for a capacity increase if the original installation was wired for increased
capacity. Operation remains the same as the original UPS. Adding the FI-UPM can
also provide N+1 redundancy if the power requirements are less than the two UPM
rating.
1.2.2
Sync Control
An optional Power Xpert 9395 Sync Control maintains the critical load outputs of two
separate single module Power Xpert 9395 UPS systems in synchronization. This
option facilitates the uninterrupted transfer of the load from one load bus to another
by means of transfer switches. The Sync Control is housed in a wall‐mounted panel
that can be located between the UPS units for easy wiring.
1.2.3
Single-Feed Kit
An optional kit is available for converting the dual-feed rectifier and bypass inputs to a
single-feed configuration. The kit consists of jumpers and bus bar extensions for each
phase, and the hardware required for installation.
1.2.4
Separate Rectifier Input
The UPS can be supplied with separate rectifier inputs for each UPM. Separate inputs
provide increased flexibility and reliability by allowing multiple input sources to supply
the UPS. Input circuit breaker CB1 is not installed with this configuration. AC input
control to the UPS and each UPM rectifier is to be supplied by the customer.
All sources that feed the separate rectifier inputs must be from a common ground
point.
1.2.5
Distributed Bypass System
There are two types of redundancy: UPS based (based on the number of UPSs) and
UPM based (based on the number of UPMs). Each UPS can contain three to four
UPMs.
A distributed bypass UPS system with two to five UPSs can be installed to provide a
capacity and/or redundant system. This load sharing system provides more capacity
than a single UPS, and can provide backup, depending on the load and configuration.
In addition, when one UPM is taken out of service for maintenance or is not operating
properly, a redundant UPM continues to supply uninterrupted power to the critical
load. A Powerware Hot Sync® Controller Area Network (CAN) Bridge Card provides
connectivity and operational mode control. The distributed bypass system consists of
two to five UPSs each with a parallel CAN card, and a customer-supplied tie cabinet
or load distribution panel to act as a tie point.
All UPSs in the distributed bypass system must contain the same number of UPMs.
Mixed UPS kVA ratings are not permitted.

1-5
INTRODUCTION
The tie cabinet must contain Module Output Breakers (MOBs) with dual auxiliary
contacts for control of the system. Without dual auxiliary MOBs, UPMs are not
allowed to go to bypass individually during servicing. All UPMs will go to bypass
instead of just the UPM needing service, decreasing critical load protection. With dual
auxiliary MOBs, one UPM can be bypassed while the remaining UPMs support the
load as long as the remaining UPMs have the capacity to do so.
1.2.6
Input Output Module Configuration
The UPS can be supplied in an Input Output Module (IOM) configuration without the
bypass input connections, the static switch, the motorized wraparound bypass
breaker, and the backfeed protection contactor. This configuration is primarily used in
multiple UPS parallel systems that do not need a bypass for each UPS and use a
separate System Bypass Module (SBM) to provide system bypass capabilities.
1.2.7
Continuous Static Switch
A continuous static switch is used to provide transfer of the load from the inverter to
the bypass source in the event the inverter become unavailable. The continuous static
switch eliminates the need for an additional motorized wraparound bypass breaker.
1.2.8
Inherent Redundancy
To deliver greater reliability, the Power Xpert 9395 UPS can be configured by an
authorized Eaton Customer Service Engineer for inherent redundancy. When
configured, the UPS automatically becomes redundant if the load is at or below the
capacity of the UPMs minus the capacity of one UPM. Under normal conditions the
UPMs in the UPS share the load equally. If one or more UPMs becomes unavailable
and the load is at or below the capacity of remaining UPMs, the remaining UPMs
supply the load instead of transferring to bypass.
If the capacity of the UPMs falls below the redundancy level or the load increases
above redundancy level, but is still able to maintain the load, a loss of redundancy
alarm is sounded. If the load exceeds the capacity of remaining UPMs, the UPS
transfers to bypass.
1.2.9
Energy Saver System and High Alert Modes
NOTE Energy Saver System mode requires the UPS to be factory built with a Continuous Static Switch
(CSS). See Table 1‐1 for applicable configuration.
NOTE The Variable Module Management System and Energy Saver System modes are mutually exclusive.
As a subset of Online mode, the Energy Saver System (ESS)mode maximizes
efficiency by eliminating unnecessary power conversion when the commercial power
source is within acceptable voltage and frequency limits. In this mode, the UPS is
actively monitoring the critical bus and instantly and seamlessly transitions to
double-conversion mode (inverter online) if a commercial electrical power brownout,
blackout, overvoltage, undervoltage, or out‐of‐tolerance frequency condition occurs.
In High Alert mode the unit transfers from ESS mode to double-conversion mode or if
in double-conversion mode remains in double-conversion mode for a default time
period of one hour. High Alert mode allows the user to place the unit in
double-conversion mode when outside conditions could cause a power disturbance.
At the completion of the time period, the unit defaults back to ESS mode. If the High
Alert command is received during the time period, the timer will be restarted.

INTRODUCTION
1.2.10
Variable Module Management System and High Alert Modes
NOTE The Variable Module Management System and Energy Saver System modes are mutually exclusive.
The Variable Module Management System (VMMS) mode maintains UPM
redundancy and achieves higher efficiencies by intelligently controlling the UPM’s
load level. The efficiency rating for each UPM is highest when loads are greater than
50% of the system rating. Therefore, shifting the load to fewer UPMs can achieve
higher efficiencies when the UPS load is lighter.
In VMMS mode, the UPS is actively monitoring the critical bus and UPMs are
available to assume load in less than 2 ms to respond to load changes.
The VMMS feature has three configurable modes of operation: Online mode, Online
mode with VMMS, and High Alert mode. All modes are selectable from the front
panel.
VMMS mode supports both distributed bypass and SBM parallel configurations.
In High Alert mode, all idle UPMs go online for one hour. At the completion of the
hour, the UPS defaults back to VMMS mode. If the High Alert command is received
during the one hour, the one hour timer will be restarted.
1.2.11
Monitoring and Communication
S Remote Monitor Panel II (RMP II) – An optional RMP II contains backlit status
indicators and a local horn, allowing monitoring of the operational status and alarm
condition of the UPS from virtually any location within the facility.
S Relay Interface Module II (RIM II) – An optional RIM II uses relay contact closures to
indicate the UPS operating status and alarm condition.
S Supervisory Contact Module II (SCM II) – An optional SCM II establishes an interface
between the UPS system equipment and the customer's monitor.
S X-Slot Cards – Optional X-Slot cards support several protocols, such as SNMP,
HTTP, IBM® AS/400®, and Modbus®.
S eNotify Remote Monitoring and Diagnostics Service – An optional service that provides
24/7 remote monitoring of 43 alarms, temperature/humidity and battery charge
information, daily heartbeat check, and monthly report. The service also provides
customer notification of significant alarms, remote diagnostics, and dispatch of
technicians. A PXGX connectivity card is required in an X-Slot communication bay.
An optional Environmental Monitoring Probe (EMP) is required for
temperature/humidity monitoring.
See Chapter 8, “Communication,” for additional information on monitoring and
communication features.

INTRODUCTION
1.3
Battery System
Although not provided with the UPS, a battery system is required to provide
emergency short-term backup power to safeguard operation during brownouts,
blackouts, and other power interruptions. The battery system should be equipped
with lead‐acid batteries. An external battery disconnect switch must be used.
The UPMs may be powered with either a common or separate battery system. In a
common battery system, single and multiple UPMs are powered from one common
battery source. In a separate battery system, multiple UPMs are each powered from
separate battery sources.
UPMs in distributed bypass and parallel systems must use a separate battery system.
A supplemental 48 Vdc shunt trip signal for the battery disconnect device is provided
by the UPS, but is not required for normal operation.
1.4
Basic System Configurations
The following basic UPS system configurations are possible:
S Single UPS with three common battery UPMs and a standalone common battery
system with a battery disconnect
S Single Plus 1 UPS with three common battery UPMs, a common battery FI-UPM,
and a standalone common battery system with a battery disconnect
S Single 825/550 UPS with two common battery UPMs and a standalone common
battery system with a battery disconnect
S Single UPS with three separate battery UPMs and a standalone separate battery
system with a battery disconnect for each UPM
S Single Plus 1 UPS with three separate battery UPMs, a separate battery FI-UPM,
and a standalone separate battery system with a battery disconnect for each UPM
S Single 825/550 UPS with two separate battery UPMs and a standalone separate
battery system with a battery disconnect for each UPM
S Distributed bypass system with two to five UPSs and a customer-supplied
tie cabinet

UPS System Power Wiring Preparation
Read and understand the following notes while planning and performing the
installation:
S Refer to national and local electrical codes for acceptable external wiring practices.

UPS INSTALLATION PLAN AND UNPACKING
S To allow for future kVA upgrades, consider installing a derated UPS using wiring
and external overcurrent protection breakers sized for a fully rated UPS.
S To allow for a future upgrade, install a two UPM model using conductors and
external overcurrent protection breakers sized the same as a fully rated 825 kVA
model.
S For external wiring, use 90°C copper or aluminum wire. Wire sizes listed in
Table 3‐4 through Table 3‐7 are for copper wiring only. If wire is run in an ambient
temperature greater than 30°C, higher temperature wire and/or larger size wire
may be necessary. Wire sizes are based on using the specified breakers.
S Wire ampacities are chosen from Table 310-16 of the National Electrical Code®
(NEC®). Specification is for copper wire with a 90°C rating.
S Material and labor for external wiring requirements are to be supplied by
designated personnel.
S If installing a maintenance bypass, a minimum of two separate feeds with
upstream feeder breakers, or a single feed with two upstream feeder breakers,
must be provided: one for the UPS or rectifier input breaker (RIB) (if installed) and
one for the maintenance bypass input. DO NOT use a single feed or a single feeder
breaker to supply both the UPS or RIB and the maintenance bypass. If a bypass
input breaker (BIB) is installed in the maintenance bypass and a single-feed UPS is
being installed, a single feed to the maintenance bypass is acceptable for supplying
both the UPS and the bypass.
S The bypass feed into this equipment uses three or four wires. The rectifier feed
into this equipment uses three wires. The phases must be symmetrical about
ground (from a Wye source) for proper equipment operation.
S If the load requires a neutral, a bypass source neutral must be provided.
S DO NOT install both a source neutral and a bonding jumper. See Table 3‐9 for
neutral bonding jumper wire sizes. The bonding jumper must be copper wire.
S Eaton UPS systems are designed to operate with two optional ground schemes.
Both configurations comply with international safety regulations (as seen on the
UPS name plate).
- 1. Internal reference generated through an earth reference. Ground current will
be equal to or less than 5% of the unit rating. This takes the form of a UPS N
bus to ground bond wire. This configuration is confirmed by reviewing the units
CTO number.
- 2. Internally generated reference which avoids ground current. By locating the
center reference inside the three phase conductors, the relationship between
the UPS source and the UPS output is maintained. This is an internal UPS
function and requires no additional work on the part of the installer or user. This
configuration is confirmed by reviewing the units CTO number.
CAUTION
SINGLE HIGH IMPEDANCE GROUND SOURCE - In North American installations, the neutral conductor from
the high impedance ground source of supply CANNOT be used. DO NOT bond the inverter center point (E12)
to ground: this is an internal UPS function and requires no additional work by the installer or user.
DUAL HIGH IMPEDANCE GROUND SOURCE - In North American installations, the neutral conductor from the
high impedance ground source of supply CANNOT be used. DO NOT bond the inverter center point (E12) to
ground: this is an internal UPS function and requires no additional work by the installer or user. Please
contact the Eaton help desk listed in Chapter 1 for additional guidance regarding dual high impedance
ground sources.

CAUTION
When selecting the most appropriate grounding scheme for your application, consider items such as:
Ground fault detector settings
Site specific specifications and requirements
Local codes and regulations
S The ISBM and UPM sections are shipped with debris shields covering the
ventilation grills on top of the sections. Do not remove the debris shields until
installation is complete. However, remove the shields before operating the UPS.
Once the debris shields are removed, do not place objects on the ventilation grills.
S In a common battery system, single and multiple UPMs are powered from one
common battery source. In a separate battery system, multiple UPMs are each
powered from separate battery sources.
S UPMs in distributed bypass and parallel systems must use a separate battery
system.
S On a UPS configured for separate rectifier inputs, all sources that feed the
separate rectifier inputs must be derived from a common ground point.
S On a UPS configured as an Input Output Module (IOM), requirements for bypass
input wiring, termination, conduit, and bypass breaker are not applicable.
S A Field Installed UPM (FI-UPM) is always designated as UPM 4.
S The Power Xpert 9395-825/550 two UPM UPS is upgradable to a fully rated 825
kVA with the addition of the FI-UPM. Because of this future upgradability, the UPS
wire and external overcurrent protection ratings listed in the following tables are
specified for 825 kVA.
If the power rating listed on the nameplate of the installed UPS is not found in the
following tables, wire the UPS using the fully rated specifications. Otherwise,
calculate the required wire, conduit, and breaker sizes using the following guidelines
in addition to those already listed in paragraph 3.2.2:
S Select wire size according to the UPS nameplate.
S Do not use wire larger than the largest size listed in Table 3‐4 through Table 3‐8.
S Use terminal recommendations from Table 3‐12 through Table 3‐15.
S Size and number of conduits must not exceed those listed in Table 3‐16.
S Select overcurrent protection input, battery, and output breakers according to the
UPS nameplate rated for either 80% or 100%.
S Follow all applicable NEC and local codes.
For three UPM external wiring requirements, including the minimum AWG size of
external wiring see:
S Table 3‐4 for common battery system installations
S Table 3‐5 for separate battery system installations
S Table 3‐8 for separate rectifier feed installations
Wire sizes listed are for copper wiring only.
For two UPM external wiring requirements, including the minimum AWG size of
external wiring see:

UPS System Interface Wiring Preparation
Control wiring for features and options should be connected at the customer interface
terminal blocks located inside the UPS.
WARNING
Do not directly connect relay contacts to the mains related circuits. Reinforced insulation to the mains is
required.
Read and understand the following notes while planning and performing the
installation:
S Use Class 1 wiring methods (as defined by the NEC) for interface wiring up to 30V.
The wire should be rated at 24V, 1A minimum.
S Use Class 2 wiring methods (as defined by the NEC) for interface wiring from 30V
to 600V. The wire should be rated at 600V, 1A minimum and 12 AWG maximum.
S Use shielded twisted‐pair wires for each input and return or common.
S All interface wiring and conduit is to be supplied by the customer.
S When installing external interface wiring (for example, building alarm, relay output,
battery breaker trip, and X-Slot) to the UPS interface terminals, conduit must be
installed between each device and the UPS cabinet.
S Install the interface wiring in separate conduit from the power wiring.
S When installing internal interface wiring to X-Slot terminals, route the wiring
through the internal opening in the X-Slot communication bay.
S All building alarm inputs or remote features require an isolated normally‐open
contact or switch (rated at 24 Vdc, 20 mA minimum) connected between the alarm
input and common terminal. All control wiring and relay and switch contacts are
customer‐supplied.
S The building alarms can be programmed to display the alarm functional name.
S LAN and telephone drops for use with X-Slot connectivity cards must be supplied
by the customer.
S The UPS battery aux signal wiring from the UPS must be connected to the battery
disconnect device.
S A supplemental 48 Vdc shunt trip signal for the battery disconnect device is
provided, but is not required for normal operation.
S Battery aux and 48 Vdc shunt trip wiring should be a minimum of 18 AWG.

S Alarm relay wiring should be a minimum of 22 AWG.
CAUTION
On all 9395 models that will be fed by a site generator at any time it is recommended to have an “On
Generator” sensing input connected and proven functional. This allows the UPS to optimize its operation
with the generator. This function includes reduced input current and battery current limits, slower walk-in to
ease the load step on the generator initially, and HIGH ALERT mode for ESS and VMMS operation.
HIGH ALERT mode is desired because any loads with a leading power factor will not be seen by the
generator. Rectifier operation will be much softer while on generator thereby increasing overall system
stability.
3.2.4
Distributed Bypass Power Wiring Preparation
Read and understand the following notes while planning and performing the
installation:
S All distributed bypass UPS rectifier inputs must come from one source and all
bypass input feeds must come from one source.
S All UPSs in the distributed bypass system must contain the same number of
UPMs. Mixed UPS kVA ratings are not permitted.
S Distributed bypass UPS input wiring size requirements and output wiring size
requirements from the UPSs to the tie cabinet or distribution panel are the same as
listed in Table 3‐4 on page 3-13, Table 3‐5 on page 3-14, Table 3‐6 on page 3-15, or
Table 3‐7 on page 3-16.
S If the load requires a neutral, a bypass source neutral must be provided.
S In the case of parallel Distributed Bypass configurations, wiring for the common
system neutral reference will also be connected to E12 of each module and this
common system neutral reference wiring will be routed to the output switchgear
cabinet and connected to an isolated / ungrounded bus which is common with the
wiring from the E12 terminal of all other paralleled modules of the Distributed
Bypass system.
S DO NOT install both a source neutral and a bonding jumper. See Table 3‐9 for
neutral bonding jumper wire sizes. The bonding jumper must be copper wire.
S Eaton UPS systems are designed to operate with two optional ground schemes.
Both configurations comply with international safety regulations (as seen on the
UPS name plate).
- 1. Internal reference generated through an earth reference. Ground current will
be equal to or less than 5% of the unit rating. This takes the form of a UPS N
bus to ground bond wire. This configuration is confirmed by reviewing the units
CTO number.
- 2. Internally generated reference which avoids ground current. By locating the
center reference inside the three phase conductors, the relationship between
the UPS source and the UPS output is maintained. This is an internal UPS
function and requires no additional work on the part of the installer or user. This
configuration is confirmed by reviewing the units CTO number.

CAUTION
SINGLE HIGH IMPEDANCE GROUND SOURCE - In North American installations, the neutral conductor from
the high impedance ground source of supply CANNOT be used. DO NOT bond the inverter center point (E12)
to ground: this is an internal UPS function and requires no additional work by the installer or user.
DUAL HIGH IMPEDANCE GROUND SOURCE - In North American installations, the neutral conductor from the
high impedance ground source of supply CANNOT be used. DO NOT bond the inverter center point (E12) to
ground: this is an internal UPS function and requires no additional work by the installer or user. Please
contact the Eaton help desk listed in Chapter 1 for additional guidance regarding dual high impedance
ground sources.
CAUTION
When selecting the most appropriate grounding scheme for your application, consider items such as:
Ground fault detector settings
Site specific specifications and requirements
Local codes and regulations
S MOBs with dual auxiliary contacts are to be supplied by the customer. Table 3‐19
on page 3-24 lists the recommended rating for the MOBs.
The tie cabinet must contain Module Output Breakers (MOBs) with dual auxiliary
contacts for control of the system. Without dual auxiliary MOBs, UPMs are not
allowed to go to bypass individually during servicing. All UPMs will go to bypass
instead of the just the UPM needing service, decreasing critical load protection.
With dual auxiliary MOBs, one UPM can be bypassed while the remaining UPMs
support the load as long as the remaining UPMs have the capacity to do so.
3.3
Inspecting and Unpacking the UPS Cabinets
The UPS cabinet is divided into two sections palleted separately for shipping. The
sections are shipped bolted to wooden pallets (see Figure 3‐15 through Figure 3‐17)
and protected with outer protective packaging material.
WARNING
The UPS sections are heavy (see Table 3‐1 on page 3-2). If unpacking and unloading instructions are not
closely followed, the cabinets may tip and cause serious injury.
CAUTION
To prevent damage to the wiring channel and wiring in the UPM section base when lifting or moving the
cabinet:
S Lift and move the UPM section using only the front or rear forklift slots.
S Verify that the forklift forks are in a horizontal position before inserting them into the forklift slots.
DO NOT angle fork tips upward.
S Insert the forks all the way through the base. DO NOT insert forks partially into the base to move the
cabinet.
S Forks may be partially inserted into the front or rear forklift slots for minor positioning if the forks are
kept in a horizontal position with no upward angling.
S DO NOT use the forklift slots on the end of the cabinet to move the cabinet.
S End forklift slots may be used for minor positioning if the forks are kept in a horizontal position with no
upward angling.

Field Installed UPM Installation
If installing a Plus 1 model or adding the FI-UPM to an 825/550 model, install the
FI-UPM using the instructions in the Power Xpert 9395 Field Installed UPM
Mechanical Installation Manual, listed in paragraph 1.8 on page 1-10. After the FI-UPM
is installed, proceed to paragraph 4.6 if installing a battery system; otherwise, proceed
to paragraph 4.7.
4.6
Battery System Installation
If installing a battery system, install the customer-supplied battery system according
to the battery and battery system manufacturer's instructions and all applicable codes
and regulations, including the NEC, Article 480. After the battery system is installed,
proceed to paragraph 4.7 if installing a distributed bypass tie cabinet; otherwise,
proceed to paragraph 4.8.
4.7
Distributed Bypass Tie Cabinet Installation
NOTE The tie cabinet must contain Module Output Breakers (MOBs) with dual auxiliary contacts for control
of the system. Without dual auxiliary MOBs, UPMs are not allowed to go to bypass individually during
servicing. All UPMs will go to bypass instead of only the UPM needing service, decreasing critical load
protection. With dual auxiliary MOBs, one UPM can be bypassed while the remaining UPMs support the load
as long as the remaining UPMs have the capacity to do so.
If installing a distributed bypass system, install the customer-supplied tie cabinet or
distribution panel according to the tie cabinet or distribution panel manufacturer's
instructions and all applicable codes and regulations, including the NEC, Article 480.
After the tie cabinet is installed, proceed to paragraph 4.8 to complete the wiring of
the UPS.
In the case of parallel Distributed Bypass configurations, wiring for the common
system neutral reference will also be connected to E12 of each module and this
common system neutral reference wiring will be routed to the output switchgear
cabinet and connected to an isolated / ungrounded bus which is common with the
wiring from the E12 terminal of all other paralleled modules of the Distributed Bypass
system.
4.8
Installing UPS External and Battery Power Wiring
NOTE The ISBM and UPM sections are shipped with debris shields covering the ventilation grills on top of
the sections (see Figure 4‐18). Do not remove the debris shields until installation is complete. However,
remove the shields before operating the UPS. Once the debris shields are removed, do not place objects on
the ventilation grills.
NOTE Remove the ISBM section top or bottom conduit landing plate to drill or punch conduit holes (see
Figure 4‐19 on page 4-22).
NOTE If the load requires a neutral, a bypass source neutral must be provided. If the load does not require
a neutral and there is no neutral conductor connected at the bypass input, a neutral to ground bonding jumper
must be installed. DO NOT install both a source neutral and a bonding jumper. See Table 3‐4 through
Table 3‐7 starting on page 3-13 for neutral bonding jumper wire sizes. Bonding jumper must be copper wire.
CAUTION
HIGH IMPEDANCE GROUND SOURCES - If the supply source is a high impedance ground (IT) type, the
neutral‐forming transformer kit must be used instead of pulling a neutral from the source. In no
circumstances shall a neutral to ground bonding jumper be installed in the UPS.

CAUTION
DELTA SOURCES (TN‐S) - The UPS cannot be operated from a mid‐point or end‐point grounded delta supply
source. With this type of supply source, there is no capability to provide an output neutral. In no
circumstances shall a neutral to ground bonding jumper be installed in the UPS.
Use the procedures in the following paragraphs to connect the external and battery
power wiring.
4.8.1
2‐Hole Barrel Lug Terminations to Bus Bar Installation
Paragraphs 4.8.2 and 4.8.3 require connecting input, output, and battery power wiring
using 2-hole barrel lugs. See Figure 4‐17 for the hardware sequence when installing
the lugs to the bus bars. Tighten the nut to the torque value listed in Table 3‐12.
NOTE Conical washers are special purpose washers that look similar to flat washers, except for a slight
conical shape. When installing conical washers, the top of the dome should be next to the nut and the base of
the washer should be against a flat surface such as a bus bar, flat washer, or large terminal.

If MOB contacts have pigtail leads, use the same wire gauge to connect to the UPS and use the correct crimp connections for the wire gauge.
External CAN connections between UPS cabinets require shielded twisted-pair wire.
Use twisted-pair wiring between the UPS and MOB AUX contacts.
Always confirm contact operation prior to wiring.

UPS System Overview
The Power Xpert 9395 UPS is a continuous-duty, solid‐state, transformerless (at
480 Vac), three-phase, true online system that provides conditioned and
uninterruptible AC power to the UPS system's output and critical load.
The basic system consists of a rectifier, battery converter, inverter,
monitoring/operation control panel, integrated communication server, and digital
signal processor (DSP) logic. Figure 6‐1 shows the main elements of the UPS system.
If utility power is interrupted or falls outside the parameters specified in Chapter 10,
“Product Specifications,” the UPS uses a backup battery supply to maintain power to
the critical load for a specified period of time or until the utility power returns. For
extended power outages, the UPS allows you to either transfer to an alternative
power system (such as a generator) or shut down your critical load in an orderly
manner.

UNDERSTANDING UPS OPERATION
The emergency bypass consists of a continuous static switch, and a backfeed
protection contactor K5. The bypass breaker (if installed) is located in parallel with the
static switch. The backfeed protection contactor is located in series with the static
switch. The static switch is armed and ready during normal operation.
On a UPS configured as an Input Output Module (IOM), bypass circuitry is not
installed. This configuration is primarily used in multiple UPS parallel systems that do
not need a bypass for each UPS and use a separate System Bypass Module (SBM) to
provide system bypass capabilities.
6.2
Single UPS
A single UPS operates independently to support an applied load from the inverter,
providing conditioned and uninterruptible AC power to the critical load from the output
of the module. During an outage, the inverter continues to operate, supporting power
to the load from the battery supply. If the unit requires service, applied loads are
transferred to the internal bypass either automatically or manually. With the exception
of a battery cabinet, no other cabinets or equipment are required for the single UPS to
successfully support its applied loads.
6.2.1
Modes
The Power Xpert 9395 UPS supports a critical load in five different modes of
operation:
NOTE The Variable Module Management System and Energy Saver System modes are mutually exclusive.
S In Online mode, the critical load is supplied by the inverter, which derives its power
from rectified utility AC power. In this mode, the battery charger also provides
charging current for the battery, if needed.
S In Energy Saver System (ESS) mode, commercial AC power is supplied directly to
the critical load through the continuous static switch and transfers automatically to
Online mode if an abnormal condition is detected. The ESS mode requires a UPS
with a continuous static switch.
S In Variable Module Management System (VMMS) mode, the UPS operates as a
traditional double conversion UPS, but selectively shifts the load to fewer UPMs to
increase the efficiency of the UPS.
S In Bypass mode, the critical load is directly supported by utility power.
S In Battery mode, the battery provides DC power, which maintains inverter
operation. The battery supports the critical load.
The following paragraphs describe the differences in the UPS operating modes, using
block diagrams to show the power flow during each mode of operation.

UNDERSTANDING UPS OPERATION
6.2.2
Online Mode
Figure 6‐2 shows the path of electrical power through the UPS system when the UPS
is operating in Online mode.
During normal UPS operation, power for the system is derived from a utility input
source through the rectifier input contactor K1. The front panel displays “Online,”
indicating the incoming power is within voltage and frequency acceptance windows.
Three-phase AC input power is converted to DC using IGBT devices to produce a
regulated DC voltage to the inverter. When contactor K2 is closed the battery is
charged directly from the regulated rectifier output through a buck or boost DC
converter, depending on the system voltage and the size of the battery string
attached to the unit.
The battery converter derives its input from the regulated DC output of the rectifier
and provides either a boosted or bucked regulated DC voltage charge current to the
battery. The battery is always connected to the UPS and ready to support the inverter
should the utility input become unavailable.
The inverter produces a three-phase AC output to a customer's load without the use
of a transformer. The inverter derives regulated DC from the rectifier and uses IGBT
devices and pulse-width modulation (PWM) to produce a regulated and filtered AC
output. The AC output of the inverter is delivered to the system output through the
output contactor K3.

UNDERSTANDING UPS OPERATION
If the utility AC power is interrupted or is out of specification, the UPS automatically
switches to Battery mode to support the critical load without interruption. When utility
power returns, the UPS returns to Online mode.
NOTE Bypass mode is not available on a UPS configured as an IOM.
If the UPS becomes overloaded or unavailable, the UPS switches to Bypass mode.
The UPS automatically returns to Online mode when the overload condition is cleared
and system operation is restored within specified limits.
If the UPS suffers an internal failure, it switches automatically to Bypass mode and
remains in that mode until the failure is corrected and the UPS is back in service.
6.2.3
Energy Saver System Mode
NOTE VMMS and ESS modes are mutually exclusive. If ESS mode is enabled, VMMS mode is disabled.
NOTE ESS mode requires the UPS to be factory built with a Continuous Static Switch (CSS).
When the UPS is operating in ESS mode, commercial AC power is supplied directly to
the critical load through the continuous static switch. Power line filtering and spike
protection for the load are provided by the input and output filter networks, and the
UPS actively monitors the critical bus for power disturbances. When in this mode, the
input and output contactors are closed and the link is maintained through the diode
bridge.
If commercial power voltage or frequency disturbances are detected, the system
forward transfers to Battery mode for minor disturbances and then to double
conversion mode for more severe disturbances. During a complete power outage, the
transfer takes place within 2 ms to ensure loads being fed by the system output are
not interrupted. All forward transfers transfer to Battery mode before returning to
double conversion mode.
In High Alert mode the unit transfers from ESS mode to double conversion mode or if
in double conversion mode remains in double conversion mode for a default time
period of one hour (customer configurable). At the completion of the time period, the
unit defaults back to ESS mode. If the High Alert command is received during the
time period, the timer will be restarted.
ESS mode is a normal operating mode, and not an alarm condition. While the UPS is
in this mode, the Online light on the front display will illuminate.

UNDERSTANDING UPS OPERATION
6.2.4
Variable Module Management System
NOTE VMMS and ESS modes are mutually exclusive. If VMMS mode is enabled, ESS mode is disabled.
In VMMS mode, the UPS operates as a traditional double conversion UPS. However,
the UPS will selectively shift the load to fewer UPMs based on the required load in
order to force the remaining UPMs to carry a higher load. The efficiency rating for
each UPM is highest when loads are greater than 50% of the system rating.
Therefore, with multiple UPMs, a UPS can achieve higher efficiencies for lighter
loads.
When a UPM is placed into VMMS mode, the UPM will stop gating the inverter and
rectifier and keep the output contactor closed in order to maintain voltage match and
phase lock to the critical bus. In this mode the UPS actively monitors the critical bus,
keeping the UPM input contactors closed in order to keep the DC link primed (through
the rectifier diodes) and also to allow the UPM to immediately return to active mode
in the event of a disturbance or load step on the critical bus.
VMMS limits the maximum power available from a UPM when in VMMS mode. The
default setting is 80% of the UPM full power rating. If the limit is exceeded, additional
UPMs take on the increased load. The VMMS redundancy setting sets the number of
redundant UPMs that the customer requires. Both the VMMS UPM load limit and
UPM redundancy are customer configurable.
VMMS's UPM automatic scheduling rotates the idle UPMs every month with the
ABM cycle. This allows the UPMs to have equal load-share time and also conducts a
periodic UPM readiness test. The automatic ABM scheduler selects the next UPM in
turn after each charge-to-float transition. If ABM is disabled, the scheduler selects the
next UPM after conducting the automatic battery test. If ABM and automatic battery
tests are disabled, the scheduler selects the next UPM at the beginning of each
month.
In High Alert mode, the UPS defaults to double conversion mode and all UPMs go
active for one hour (customer configurable). At the completion of the hour, the UPS
defaults back to VMMS mode. If the High Alert command is received during the one
hour, the one hour timer will be restarted.

6.2.5
Bypass Mode
NOTE Bypass mode is not available on a UPS configured as an IOM.
The UPS automatically switches to Bypass mode if it detects an overload, load fault,
or internal failure. The UPS can also be transferred from Online mode to Bypass mode
manually. The bypass source supplies the commercial AC power to the load directly.
Figure 6‐3 shows the path of electrical power through the UPS system when
operating in Bypass mode.
In Bypass mode, the output of the system is provided with three-phase AC power
directly from the system input. While in this mode, the output of the system is not
protected from voltage or frequency fluctuations or power outages from the source.
Some power line filtering and spike protection is provided to the load but no active
power conditioning or battery support is available to the output of the system in the
Bypass mode of operation.
The internal bypass is comprised of a SCR continuous static switch, and a backfeed
protection contactor K5. The static switch is used instantaneously anytime the
inverter is unable to support the applied load. The continuous static switch is wired in
series with the backfeed protection contactor, and together they are wired in parallel
with the rectifier and inverter.
CAUTION
The critical load is not protected from voltage or frequency fluctuations or power outages while the UPS is in
Bypass mode.
The static switch, being an electronically-controlled device, can be turned on
immediately to pick up the load from the inverter while inverter output contactor K3
opens to isolate the inverter. The backfeed protection contactor is normally closed,
ready to support the static switch unless the bypass input source becomes
unavailable.

Figure 6‐3. Path of Current Through the UPS in Bypass Mode
If the UPS transfers to Bypass mode from Online mode due to any reason other than
operator intervention, the UPS automatically attempts to transfer back to Online
mode (up to three times within a ten minute period). The fourth transfer locks the
critical load to the bypass source and requires operator intervention to transfer.
6.2.6
Battery Mode
The UPS automatically transfers to Battery mode if a utility power outage occurs, or if
the utility power does not conform to specified parameters. In Battery mode, the
battery provides emergency DC power that the inverter converts to AC power.
Figure 6‐4 shows the path of electrical power through the UPS system when
operating in Battery mode.
During a utility power failure, the rectifier no longer has an AC utility source from
which to supply the DC output voltage required to support the inverter. The input
contactor K1 opens and the battery instantaneously supplies energy to the battery
converter. The converter boosts the voltage so that the inverter can support the
customer's load without interruption. If bypass is common with the rectifier input, the
backfeed protection contactor K5 also opens. The opening of contactors K1 and K5

Figure 6‐4. Path of Current Through the UPS in Battery Mode
If the input power fails to return or is not within the acceptance windows required for
normal operation, the battery continues discharging until a DC voltage level is reached
where the inverter output can no longer support the connected loads. When this
event occurs, the UPS issues another set of audible and visual alarms indicating
SHUTDOWN IMMINENT. Unless the rectifier has a valid AC input soon, the output
can be supported for only two minutes before the output of the system shuts down.
If the bypass source is available, the UPS transfers to bypass instead of shutting
down.
If at any time during the battery discharge the input power becomes available again,
contactors K1 and K5 close and the rectifier begins to supply DC current to the
converter and inverter. At this point, the unit returns to Online mode. Depending on
the total load and the duration of the battery discharge, battery current limit alarms
may be seen for a short time due to the current required to recharge the battery.

Multiple UPS Distributed Bypass System
Distributed bypass parallel operation extends the normal operation of Power Xpert
9395 UPSs by offering increased capacity and/or redundant capability. The parallel
system continues to maintain power to the critical loads during commercial electrical
power brownout, blackout, overvoltage, undervoltage, and out‐of‐tolerance frequency
conditions.
The output of the system is normally supplied by Uninterruptible Power Modules
(UPMs) contained in each UPS. Multiple UPMs are connected with their outputs in
parallel (tied together) to provide a load level greater than the rating of one UPM, for
redundancy, or both. The paralleled UPMs supply the output load with protected
power as long as the load does not exceed the combined rating of the paralleled
UPMs.
The power system is redundant as long as one of the UPMs can be disconnected
from the output bus and the remaining UPMs can continue to supply power to the
load without exceeding their ratings.
When the load is being supplied by the UPMs, the system output bus is continuously
monitored for an overvoltage or undervoltage condition. If an out of limits condition is
detected, the paralleled UPMs transfer the load to bypass using the UPS static
switches.
Communication is required between the UPSs for system metering and mode
control. System level communication and control are accomplished using a Controller
Area Network (CAN). A single building alarm in each UPS, connected to the other
UPSs in parallel and tied to the bypass contactor auxiliary contacts in each UPS, are
used for a secondary communication path. This arrangement ensures bypass control
even if the CAN bus is lost.
The system is paralleled for redundancy (1+1) in a system where two UPMs are
paralleled together and the load is less than the supporting capability of one of the
UPMs. The system is paralleled for capacity (2+0) if both UPMs in a system are
required to support the load.
A parallel capacity system can also be redundant (2+1), as long as there is always one
or more UPMs online than required to support the load.
6.4.1
Multiple UPS Parallel System Modes
Similar to the single UPS system, the Power Xpert 9395 UPS parallel system supports
a critical load in five different modes of operation. The standard operation modes are:
NOTE The Variable Module Management System and Energy Saver System modes are mutually exclusive.
S In Online mode, the paralleled UPMs supply the critical load with clean, filtered
power. Each UPM battery charger also provides charging current for the battery if
needed.
S In ESS mode, commercial AC power is supplied directly to the critical load through
the continuous static switch and transfers automatically to Online mode if an
abnormal condition is detected. The Energy Saver mode requires a UPS with a
continuous static switch. ESS mode in a parallel system operates the same as it
does in a single UPS system (see paragraph 6.2.3).
6-30
t 9395 UPS (450–825 kVA) Installation and Operation Manual
Power Xpert
S 164201725 Rev 6 www.eaton.com/powerquality
UNDERSTANDING UPS OPERATION
S In VMMS mode, the UPS operates as a traditional double-conversion UPS, but
selectively shifts the load to fewer UPMs to increase the efficiency of the UPS. In
a parallel system each UPS will require at least one UPM to be in double
conversion mode at all times; otherwise, VMMS mode operates the same as it
does in a single UPS system (see paragraph 6.2.4).
S In Bypass mode, the critical load is directly supported by utility power through the
bypass circuit in each UPS.
S In Battery mode, the battery provides DC power, which maintains UPM operation.
The UPM batteries support the critical load.
The UPSs continually monitor themselves and the incoming utility power and
automatically switch between these modes as required, without operator
intervention, except when manually switching to Bypass mode. The sophisticated
detection and switching logic inside the UPSs ensures that operating mode changes
are automatic and transparent to the critical load, while internal monitoring systems
indicate the current mode of operation. The UPSs switch operating modes in
response to these system events:
S A command is an intervention that is externally initiated by an operator or by some
site action. A command causes the UPSs to switch operating modes; it usually
does not require any further action.
S A notice is a minor system event that may or may not require attention.
S An alarm is a system event that requires immediate intervention.
The following paragraphs describe the differences in the parallel system operating
modes, using block diagrams to show the power flow during each mode of operation.
6.4.2
Online Mode – Distributed Bypass
In Online mode, utility AC power is supplied to the UPSs. Each UPS then conditions
the incoming AC power and provides clean, regulated AC power to the tie cabinet or
distribution panel for parallel systems up to four modules. The applied load is shared
equally among the available UPMs in the system.
Figure 6‐24 shows the path of electrical power through the parallel system when
operating in Online mode.
If the utility AC power is interrupted or is out of specification, the UPSs automatically
switch to Battery mode to support the critical load without interruption. When utility
power returns, the UPSs return to Online mode.
If the UPSs become overloaded or unavailable, the distributed bypass system
switches to Bypass mode. The distributed bypass system automatically returns to
Online mode when the overload condition is cleared and system operation is restored
within specified limits.

protected from fluctuations, spikes, or power outages from the source. No battery
support is available to the output of the system in the Bypass mode of operation.
The distributed bypass system automatically switches to Bypass mode if it detects a
UPS system overload or load fault.
If one UPS becomes unavailable, the distributed bypass system dynamically updates
the redundancy calculation to determine if the remaining UPSs can support the load.
If the load can be supported, the system does not switch to bypass.
Figure 6‐25 shows the path of electrical power through the parallel system when
operating in Bypass mode.
In a distributed bypass system, each UPS operates similar to a single UPS, but in
parallel with each other. The bypass source for the load is derived from the bypass
input of one, two, three, or four UPSs, depending on the system configuration,
through the internal static switches. If a module is taken offline, the other modules
remain online to support the load. If more modules than can support the load must be
taken offline, the load must be transferred to maintenance bypass or shut down.

Figure 6‐25. Path of Current through the UPSs in Bypass Mode – Distributed Bypass
The distributed bypass system can be transferred from Online mode to Bypass mode
manually. However, the distributed bypass system automatically switches to Bypass
mode whenever the UPSs can no longer supply the critical load. If the distributed
bypass system transfers to Bypass mode from Online mode due to an output voltage
deviation, the distributed bypass system automatically attempts to return to Online
mode (up to three times within a 10‐minute period). After three transfer attempts or
an overload, the system locks the critical load to the bypass source and requires
operator intervention to transfer.
Bypass mode is a normal operating mode, not an alarm condition. However, if the
distributed bypass system is unable to return to Online mode following an automatic
transfer to Bypass mode, an alarm condition is recorded.
Bypass may also be used when the UPSs or UPMs in the system must be shut down
to perform routine maintenance or repairs.
In the Parallel Redundant (N+1) arrangement, the bypass circuitry in each UPS
operates to support the applied loads on bypass. If the UPSs are online and one UPS
trips offline, the remaining UPSs do not go to bypass as long as they have the
capacity to support the load.
In the Parallel Capacity (N+0) arrangement, if one UPS trips offline and goes to
bypass, the remaining UPSs also go to bypass.

6.4.4
Battery Mode – Distributed Bypass
The UPSs transfer to Battery mode automatically if a utility power outage occurs, or if
the utility power does not conform to specified parameters. In Battery mode, the
battery provides emergency DC power that the inverter converts to AC power.
Figure 6‐26 shows the path of electrical power through the distributed bypass system
when operating in Battery mode.
While in Battery mode, the UPSs sound an audible horn, illuminate a visual indicator
lamp on the front panel (Online and On Battery), and create an entry into the alarm
event history. As the battery discharges, the boost converter and inverter constantly
make minute adjustments maintaining a steady output. The UPSs remain in this
operating mode until the input power to the rectifier is again within the specified
voltage or frequency acceptance windows.
If the input power fails to return or is not within the acceptance windows required for
normal operation, the battery continues discharging until a DC voltage level is reached
where the inverter output can no longer support the shared loads. When this event
occurs, each UPS issues another set of audible and visual alarms that indicate a
two-minute SHUTDOWN IMMINENT warning. Unless the system has a valid AC
input soon, redundant UPMs begin shutting down until there are no longer enough
UPMs online to support the connected load. When this event occurs, the system
shuts down. If the bypass source is available, the system transfers to bypass instead
of shutting down.

If at any time during the battery discharge the input power becomes available again,
the rectifier begins to supply DC current to the inverter. At this point, the UPS returns
to Online mode. If at any time during the battery discharge the AC input power
becomes available again, each rectifier turns on, assumes the inverter load from the
batteries, and begins recharging the batteries. Depending on the total load and the
duration of the battery discharge, battery and rectifier input current limit alarms may
be seen for a short time due to the current required to recharge the batteries.

events screen. This screen shows any currently active alarms, notices, or commands.
For more information on using the events screen, see paragraph 7.2.6 on page 7-6.
S System Event Horns – The system event horn beeps to alert an operator that an
event needing attention is taking place. The horn cycles at a half-second rate.
S System Event Indicators – The status indicators on the UPS control panel work with
the event horn to let the operator know when the UPS is operating in any mode
other than normal. Only the ON indicator is visible during normal UPS system
operation. The other indicators illuminate to indicate alarms or events. When an
alarm occurs, first check these indicators to see what type of event has taken
place. For descriptions of the status indicators, see paragraph 7.2.1.
S System Event Messages – When a system event occurs, a message appears on the
LCD in the UPS status area. This message is also written to the Active Events Log
and may be added to the History Log. The messages are divided into four
categories: alarms, notices, status, and commands.

Using the Remote Emergency Power-off Switch
A UPS emergency power-off is initiated by the REPO pushbutton switch. In an
emergency, you can use this switch to control the UPS output. The REPO switch
de‐energizes the critical load and powers down the UPSs immediately, without asking
for verification.
The UPS, including Bypass, remains off until restarted.
CAUTION
All power to the critical load is lost when the REPO switch is activated in the following step. You should use
this feature only when you want to de‐energize the critical load.
NOTE The following instructions are for the Eaton-supplied REPO switch. If a customer-supplied REPO
switch is used, it may not activate in the same manner; refer to the operating instructions provided with the
switch.
To use the REPO switch:
1.
Firmly push the red pushbutton until it locks into place. The switch latches into
the activated state (see Figure 7‐7).
The input, output, and bypass backfeed contactors open, the battery breaker or
disconnect is tripped, and the power module is turned off immediately, without
asking for verification on all UPSs.
CAUTION
Do not attempt to restart the system after the REPO until the cause of the shutdown has been identified and
cleared.
2.
To deactivate the REPO switch in preparation for restarting the UPS, insert the
supplied key and rotate clockwise until the red pushbutton releases (see
Figure 7‐7). To remove the key, rotate the key back to the vertical position.

The Power Xpert 9395 UPS has four standard, factory‐installed X-Slot communication
bays. See Figure 4‐25 on page 4-31 for bay locations. The UPS is compatible with the
following X-Slot cards (see Figure 8‐1):
S Power Xpert® Gateway Card – provides a data gateway from the UPS to the Power
Xpert software; provides remote monitoring through a Web browser interface,
e-mail, and a network management system using SNMP; connects to a
twisted-pair Ethernet (10/100BaseT) network. Modbus TCP support provides direct
integration of the UPS parameters to a Building Management System (BMS). It has
a built-in switching hub that allows one additional network device to be connected
to the network without the requirement of an additional network drop.
S Modbus Card – provides direct integration of UPS information (meters and status)
to a Building Management System (BMS) using the Modbus RTU protocol.
S Relay Interface Card (AS/400) – has isolated dry contact (Form-C) relay outputs for
UPS status: Utility failure, Low battery, UPS alarm/OK, or On bypass when
interfacing with IBM AS/400 computers, other relay connected computers, and
industrial applications.
S Industrial Relay Card (IRC) – indicates the operating status of the UPS system
using the customer's monitoring equipment. The IRC uses four isolated
normally-open or normally-closed dry relay contacts to indicate the UPS status.
Online, Bypass, Battery, and Alarm modes can be monitored.
S Powerware Hot Sync CAN Bridge Card – provides connectivity for operational
mode control and metering of a parallel system at any UPM in the system. In
addition, this card can be used to connect optional system monitoring devices,
such as a Remote Monitor Panel II (RMP II), a Relay Interface Module II (RIM II), or
a Supervisory Contact Module II (SCM II) to the UPS.
LAN drops for use with X-Slot connectivity cards must be provided by facility planners
or the customer.
For installation and setup of an X-Slot card, contact an Eaton service representative
(see page 1-11). Refer to the manual supplied with the X-Slot card for user
instructions.

current and historical, is analyzed at the Customer Reliability Center (CRC) for
trending issues. A set of factors, or rules, compared against your UPS's data can
indicate a potential impending failure and trigger an appropriate anomaly
notification to a CRC Analyst. Critical events are checked for additional anomalies.
Through this service, the CRC can take pre-emptive, corrective action to ensure
the highest level of availability of your Power Xpert 9395 UPS.
S The Customer Monitoring Report delivers information about Eaton's analysis of
your Power Xpert 9395 UPS on a monthly basis. Depending on the model, the
report provides detailed information about voltages, loads, external factors such as
temperature and humidity, the attached batteries, and system availability. All of
these factors contribute to the Relative Health Index (RHI) score that allows you to
compare your unit's health relative to Eaton's optimum UPS operating levels.

Installing eNotify Service
A quick start guide and self-installation wizard tool are available on the Web at
www.eaton.com/enotify/. For the latest updates, installation tips, and information on
connecting eNotify, visit the eNotify Web page. For installation support or questions
about the eNotify Service, contact www.eaton.com/enotify/.
The eNotify Service relies on a Power Xpert Gateway card installed with the UPS
sending one-way status and event e-mails to Eaton Remote Monitoring servers that
analyze and store the data. Those servers also take the appropriate actions of sending
notifications and reports. The PXGX Connectivity Card gathers information from the
UPS directly and from any external sensors that are attached. The card also records all
events that are generated by the UPS. This data is stored within the non-volatile
memory logs on the PXGX Connectivity Card.
The eNotify Service runs on common protocols and transport mechanisms, making
the connectivity between the Power Xpert 9395 UPS and the Eaton Remote
Monitoring servers easy to set up. By using common e-mail transport mechanism,
you do not have to open your network to proprietary or potentially unsecure protocols
and transports.

8.4
Building Alarm Monitoring
This standard feature lets you connect the UPS to your building alarms, such as
smoke detectors or overtemperature alarms. The customer interface terminals for
external connections are located inside the UPS. You should use twisted-pair wires
for each alarm input and common.
The building alarms can be programmed to display the alarm functional name.
8.5
General Purpose Relay Contact
One general purpose relay contact is provided as a standard feature on the UPS. The
alarm contact is located inside the UPS on the customer interface terminal board.
You can use a normally-closed or normally-open contact. If the state of the contact
changes from the state you specify as normal, a signal is issued. You can connect this
contact to equipment at your facility (such as a light or an alarm bell) to let you know
when an alarm is active on the UPS. This feature is useful if the UPS is located in a
remote area where the UPS horn may not be heard immediately.
CAUTION
Contacts should not be operated in excess of 30 Vac @ 5A maximum.

UPS Maintenance
The components inside the UPS cabinet are secured to a sturdy metal frame.
All repairable parts and assemblies are located for easy removal, with very little
disassembly. This design allows authorized service personnel to perform routine
maintenance and servicing quickly.
You must schedule periodic performance checks of your UPS system to keep it
running properly. Regular routine checks of operation and system parameters enable
your system to function efficiently for many trouble‐free years.
9.1
Important Safety Instructions
Remember that your UPS system is designed to supply power EVEN WHEN
DISCONNECTED FROM THE UTILITY POWER. The UPS module interiors are unsafe until
the DC power source is disconnected and the electrolytic capacitors are discharged.
After disconnecting the utility power and the DC power, authorized service personnel
should wait at least five minutes for capacitor bleedoff before attempting internal
access to the UPS module.
WARNING
S Servicing and maintenance should be performed by qualified service personnel only.
S LETHAL VOLTAGE PRESENT. This unit should not be operated with the cabinet doors open or protective
panels removed. Do not make any assumptions about the electrical state of any cabinet in the UPS
system.
Because each battery string is an energy source in itself, opening the battery circuit
breaker does not de‐energize the voltage within the battery string. DO NOT ATTEMPT
TO ACCESS ANY INTERNAL AREA OF THE BATTERY STRING YOURSELF. VOLTAGES ARE
ALWAYS PRESENT IN THE BATTERY STRING. If you suspect that a battery string needs
service, contact an Eaton service representative.
If the string requires service, refer to the battery manufacturer's operating manual for
instructions on battery maintenance or contact an Eaton service representative.
Observe these precautions when working on or around batteries:
S Remove watches, rings, or other metal objects.
S Use tools with insulated handles.
S Wear rubber gloves and boots.
S Do not lay tools or metal parts on top of batteries.
S Disconnect the charging source prior to connecting or disconnecting terminals.
S Determine if the battery is inadvertently grounded. If it is, remove the source of the
ground. Contact with any part of a grounded battery can result in electrical shock.
The likelihood of such shock is reduced if such grounds are removed during
installation and maintenance.
S When replacing batteries, use the same number of sealed, lead‐acid batteries.
S Proper disposal of batteries is required. Refer to your local codes for disposal
requirements.
