CHAPTER

INTRODUCTION
The Avayat RS9 uninterruptible power system (UPS) is a modular UPS
that contains battery modules and power control modules (referred to as
power modules). These modules plug into a rack cabinet structure
containing additional control, communication, and display functions
that enable integrated control of all power modules. The UPS is housed
in a single cabinet, with extra battery capacity housed in auxiliary
battery cabinets.
Power Modules
The pluggable power modules can be removed and replaced
(hot-swapped) without powering the UPS down if the UPS has sufficient
redundant capacity. Battery modules may also be hot-swapped for
maintenance. Power control circuitry in the cabinet senses problems in
power modules, and automatically transfers control and load to the
remaining power modules.
All power modules share the load requirements equally. For example,
three power modules are capable of supplying a total of 9 kVA. If a load
requires only 4.5 kVA, each power module supplies 1.5 kVA to the
output. If one power module is removed or for some reason fails, each of
the two remaining power modules would supply half of the load, or
2.25 kVA. In other words, redundancy exists when the load can be
supplied by less than all of the installed power modules.
Battery Configurations
The Avaya RS9 UPS has two different options for additional battery
configurations:
S External Battery Module Cabinet (EBMC) - this cabinet is recommended
for applications that require less than one hour of run time. One
EBMC can be connected to the UPS.
S Extended Battery Cabinet (EBC A through F) - this cabinet is recommended
for applications that require more than one hour of run time. Up to
two EBCs can be connected to the UPS.

Introduction
Battery Charger Modules
NOTE One battery charger module is required whenever one or two EBCs are used.
A 9 kVA UPS system with 13 or 14 battery strings also requires one battery charger
module.
The optional battery charger module is designed to provide additional
current for faster recharging of UPS battery modules in systems with
many batteries. It is capable of providing up to 20 amperes of current for
optimum charging, based upon the condition and number of batteries in
the system.
The battery charger module is similar in appearance to a power module.
The primary difference is the light-purple colored front label. It can be
plugged into any UPS cabinet slot above the battery modules.
The battery charger module operates in automatic modes within the UPS
cabinet under control of the UPS power modules. It communicates
through a controller area network (CAN) bus with the power modules.
The power modules monitor and control the battery charger. Alarm
conditions detected by the battery charger module are logged and
announced by the UPS system (see “Alarm Log” on page 38). Normal
output voltage is 133 Vdc.
Safety Warnings
Read the following precautions before you install the UPS.

INSTALLATION SETUP
This chapter explains how to setup and install the Avaya RS9 cabinets:
S Clearances and location requirements
S UPS Setup
S Moving the cabinets
Equipment Clearances
All cabinets require the following clearances to allow for servicing and
adequate ventilation:
S From the side panels: 6I (15.2 cm)
S Top and back: 12I (30.5 cm)
S Front: 36I (91.5 cm)
If flexible conduit connects the UPS to the service input and load
distribution panels, you may be able to gain access for servicing by
moving the UPS. If this is the case, you must still leave 12I (30.5 cm)
clearance at the back and 6I (15.2 cm) at the sides of the UPS for
ventilation.
NOTE Do not block the ventilation holes on each side and the back of the unit.
Location Requirements
Install the Avaya RS9 UPS as close as possible to the equipment or
the load distribution panel it will protect. If this distance is more than
25 ft (7.6m), transient noise can reappear in the electrical distribution
system.
If a separate battery cabinet is installed (either an External Battery
Module Cabinet or Extended Battery Cabinet), the battery cabinets must
be adjacent to the Avaya RS9 UPS.

OPERATION
The Avaya RS9 UPS operates in several different modes. Normally it
operates under internal control, called Auto mode, to automatically
protect loads connected to it. It also functions under operator control to
enable manual override should servicing or testing be required.
Figure 18 is an illustration of the operating modes. In Auto mode, the
UPS automatically switches between modes depending on line and load
conditions.
Double Conversion
(Line Conditioning)
Internal Bypass
Battery
Off
Figure 18. UPS Operating Modes Under Auto Mode Control
Double Conversion mode produces output power from the internal DC
bus. The AC input power is rectified and boosted to supply this DC bus.
The UPS switches automatically to and from Battery mode with no
interruption (0 ms transfer time) as AC input power drops and returns.
Batteries are charged in this mode.
Battery mode produces power from the batteries to supply the internal
DC bus.
Internal Bypass (Bypass) mode shunts power flow around the DC/AC
internal circuitry to keep the output powered with no line conditioning.
Electromagnetic interference (EMI) and surge circuitry still protect the
loads from voltage spikes and noise.
Avayat RS9 UPS (9–18 kVA, 9-Slot Models) Site Preparation, Installation and Operator’s Manual S 164201543 Rev A
31
Operation
Off mode turns off the output and most internal circuitry. Within this
mode, another mode (Sleep) turns off all internal circuitry when AC line
is not present and battery voltage drops to a low threshold. If AC input
voltage is not present in Off mode, the user can direct the UPS to enter
Sleep mode by selecting the Battery Protect (BP) feature (see “Removing
Input Power” on page 33). When AC input voltage returns in the Off
mode (caused by a low battery alarm condition), the UPS automatically
recovers and, if the Auto Restart parameter is enabled, switches to
Double Conversion. Auto Restart is enabled as a factory-default.
After a discharge and subsequent low-battery shutdown, the UPS will
automatically recover from Sleep mode if the Auto Restart parameter is
enabled.

Avayat RS9 UPS (9–18 kVA, 9-Slot Models) Site Preparation, Installation and Operator’s Manual S 164201543 Rev A
Operation
If the UPS has been manually set to operate in Bypass or Battery mode,
change the System Control Mode Preference (menu 4-1) selection to
Auto to return to normal Auto mode operation.
NOTE The UPS will not start operating if AC input voltage or frequency is beyond
acceptable limits or if the system mode selection is set to Battery. The UPS can not go
directly from Off to Battery.
Removing Input Power
Always put the Avaya RS9 UPS into the Off mode before removing input
power. Avaya RS9 system batteries will discharge if the input line
voltage is disconnected or turned off without first turning off the Avaya
RS9 UPS.
If the input power source will be disconnected or turned off for more
than a day or two, you should put the UPS into Sleep mode. Do this by
turning the UPS off, removing AC input power, and then pressing the
ON button and selecting Battery Protect (BP). Sleep mode allows the
UPS to remain unpowered for up to six months without having to
remove or recharge batteries.
Failure to properly power down the Avaya RS9 UPS could permanently
damage any installed batteries. Also, if batteries become severely
discharged, the UPS might not start immediately when input power is
restored.

Communication Slots
Dedicated Input Signals
S DB-9 Communication Port
LanSafe Power Management Software
Each Avaya RS9 UPS ships with LanSafe Power Management Software
and an interface cable. To begin installing LanSafe software, see the
instructions accompanying the Software Suite CD.
LanSafe software uses an RS-232 serial link to communicate with the
UPS, and it provides you with up-to-date graphics of UPS power and
system data and power flow. It also gives you a complete record of
critical power events, and it notifies you of important UPS or power
information. If there is a power outage and the Avaya RS9 system battery
power becomes low, LanSafe software can automatically shut down your
computer system to protect your data before the UPS shutdown occurs.
Avayat RS9 UPS (9–18 kVA, 9-Slot Models) Site Preparation, Installation and Operator’s Manual S 164201543 Rev A

Communication
Optional Internal Web/SNMP Card
This card provides the Avaya RS9 system with its own ethernet network
connection, allowing it to be remotely monitored and controlled via
industry-standard internet browsers. The HTML interface enables UPS
monitoring and management from anywhere on the internet or within
your intranet. In addition, third-party Simple Network Management
Protocol (SNMP) software packages may also be used to communicate
remotely with the Avaya RS9 system.
The Web/SNMP Card also allows UPS-dependent computer systems to
automatically shut down during extended power outages using the
NetWatch client software provided on the Software Suite CD.
Optional Relay Card
The relay card provides true relay contact output to peripheral devices.
Outputs are user-selectable as normally open or normally closed. Refer
the instructions included with the relay card for more detail.
Communication Slots
The Avaya RS9 UPS has two communication slots that allow quick
installation of the optional Web/SNMP card or other similar
communication interfaces. These interface cards extend the capabilities
of the Avaya RS9 system to provide compatibility with network and
remote monitoring/management systems.

Communication
Dedicated Input Signals
Emergency Power-Off: Connection to a facility Emergency Shutdown
switch provides a method for emergency Avaya RS9 system shutdown.
Opening this connection creates an immediate shutdown of the Avaya
RS9 UPS output.
On-Generator: An external signal that the input power is being supplied
by a generator. Closure of this contact causes the UPS to change the
following parameters to preset values that are designed to optimize
performance during periods of generator instability:
S Phase Lock Window and Frequency Slew Rate. These parameters
increase the rate at which the UPS tracks the input line, which causes
fewer recognized line faults during generator instability.
S Frequency Glitch Count. This parameter increases the number of bad
frequency cycles before the unit transfers to battery power. This
allows the UPS to operate smoothly during generator instability
without transferring to battery.
S Maximum Delta and Line Delta. These parameters widen the
acceptable input voltage range, allowing the UPS to ignore any
transient voltage regulation problems a generator may experience
during unstable periods.
These parameters are also available to trained service personnel through
the Service Menu.
See Figure 7 on page 14 and Figure 11 on page 17 to make the
connection for all dedicated input signals.

Maintenance
Storage Temperature
Store the Avaya RS9 battery modules (in the UPS or External Battery
Module Cabinet) at –20 to +40°C (–4 to +104°F). Batteries will have a
longer shelf life if they are kept below +25°C (+77°F). The remaining
components may be stored at –40 to +60°C (–40 to +140°F).
Battery Replacement
The Avaya RS9 hot-swappable feature allows you to replace the battery
modules easily without disconnecting the load or damaging the
batteries.
NOTE The Avaya RS9 UPS will operate with uncharged (or no) batteries, but will have
limited (or no) battery backup capability. Backup protection requires at least three
internal battery strings (two battery modules installed side-by-side equals one string)
unless an Extended Battery Cabinet is used. If an EBC is used, only one internal battery
string is required. The UPS may indicate an alarm with no batteries present.
Use the following procedure to replace battery modules in pairs.
1. Remove the front cover panel(s) from the battery modules you
need to replace.
The panels have spring latches on the left and right sides that
hold them in place.
2. Grasp the battery module handle and press down on the latch
release.
3. Pull the module out approximately 7I (17 cm) to the secondary
stop on top of the module.
4. Press down on the secondary stop release, pull the module out
further, and support the module weight with your second hand
as you remove the module from the cabinet. Remove the
battery module beside the first in a similar manner. Label the
original modules with masking tape or some other identifier.
5. After removing a pair (one string) of battery modules, install a
replacement pair. Replacements may be installed in empty
cabinet slots before removing original battery modules.

Alarm Message
What It Means
What to Do
A Low Battery
The UPS has shut down after running
on battery and discharging the
batteries.
Wait for AC input power to be restored. When AC input
power returns, the UPS begins recharging batteries and
applies power to the load.
C High Battery
The battery voltage is too high
because of a charger problem,
battery problem, or incorrect
parameter setting.
Contact your Avaya service representative.
E Low AC Output
The UPS has shut down because the
AC output voltage is too low to
provide power to the load.
Contact your Avaya service representative.
F High AC Output
The UPS has shut down because the
AC output voltage is too high.
Contact your Avaya service representative.
S High AC Input
The AC input voltage is too high; any
further increase to the voltage may
damage the UPS.
This alarm automatically clears when input voltage
returns to normal limits. The UPS will continue to support
the load until the batteries are depleted.
G Output Overload
The load is requiring more power
than the UPS power modules are
capable of supplying, and the UPS
has switched to Bypass mode.
Switch off your equipment one piece at a time until the
alarm stops.
I Overload Shutdown
The UPS has shut down due to
excessive load.
Remove excess load(s) from the UPS output and restart
the UPS by pressing the ON button through the front
panel display.

What It Means
What to Do
B Near Low Battery
The battery voltage has reached the
Near Low Battery set point.
If the voltage increases, the alarm clears automatically. If
it drops further, it will cause a Low Battery alarm.
D Low Runtime
Batteries in the unit are nearly
discharged.
Perform an orderly shutdown of all equipment and wait
for AC input power to return. When AC input power
returns, the UPS begins recharging batteries and
automatically restarts.
