tolerance. The inverter must be on. A forced transfer requires a power
interruption to the load of 0.8 seconds.
H. Forced shutdown (inverter to bypass): (While holding the Security key down)
stops the inverter and transfers the load to the AC bypass source even if the
bypass is out of tolerance. A forced transfer requires a power interruption to the

During normal operation, the UPS supports the critical load with conditioned
power. The green line indicates the power flow from the utility/mains through the
UPS systems and the static switch cabinet to the load.
On-battery Operation
If the AC input supply fails or goes out of tolerance, the UPS transfers to on-battery
operation. During on-battery operation, battery power ensures uninterrupted
support to the critical load. When the AC input supply returns, the UPS
automatically returns to normal operation.
If the batteries become depleted before the AC input supply returns, the attached
load is transferred to the AC bypass supply if it is available.

A. System load informations.
Perform a Total Power Off
NOTE: Pressing the emergency power off (EPO) key disconnects the attached
load. The EPO is to be used during emergency situations only (if provided), where
a hazard to personnel or equipment exists. Do not use the EPO for normal
shutdown of the UPS.
1. Press the optional EPO key on the front panel of the UPS or the remote EPO
key located in the room.
Uninterrupted Transfer Conditions
To transfer the load between the UPS unit and the bypass source without
interruption, the following conditions must be met:
•
The inverter output and bypass input must be synchronized.
•
The bypass AC input voltage must be within 10% of nominal voltage.
•
The bypass AC input frequency must be within specified tolerance.
Provided that both the UPS unit and the bypass AC input sources meet these
conditions, uninterrupted transfers can take place. If these conditions are not met,
transfers cannot take place without interruption to the load and a forced transfer is
required (see Forced Transfers, page 38 for more information).
Single System Start up from Off/Maintenance Bypass Operation
NOTE: If the system does not include the maintenance bypass option, start-up
only requires that you close the static bypass input breaker (Q4S) to supply the
bypass source to the connected load.
1. Close the upstream circuit breaker supplying power to the static bypass input
breaker (Q4S).
2. Close the upstream circuit breaker supplying power to the UPS input breaker
(Q1).
3. Close the optional maintenance bypass circuit breaker (Q3BP) if present. The

Operation Procedures
7. Close the UPS input breaker (Q1) and verify the following (if these conditions
are not present, there is a fault in the system. Open the UPS input breaker (Q1)
and contact Customer Support):
a. The red Load not protected LED is on.

tolerance) a forced transfer is required.
Single System Shut Down from Normal to Maintenance Bypass Operation
CAUTION
HAZARD OF EQUIPMENT DAMAGE
If the inverter is not synchronized with the bypass input, the procedure will result
in a power interruption to the load.
Failure to follow these instructions can result in injury or equipment
damage.
NOTE: If the inverter does not turn off after step 1, proceed to do a forced transfer.

CAUTION
HAZARD OF EQUIPMENT DAMAGE
If the power to Q1, Q4S, and Q3BP is supplied from the same upstream
circuit breaker, this step will interrupt the power to the load.
Failure to follow these instructions can result in injury or equipment
damage.
Parallel System Start up from Off/Maintenance Bypass Operation

programmed for automatic restart, press the Inverter on key. The green
Load protected LED will flash for about three seconds, indicating that the
inverter is starting.
e. As soon as a sufficient number of UPS units have been started, the SSC will
automatically transfer the load to the UPS unit output. On each UPS unit, the
green Load protected LED will turn on and remain on. On the SSC, the
green Load protected LED will turn on.
f. As the remaining UPS units are turned on, their respective green Load
protected LEDs will flash for three seconds, then remain on as the modules
connect to the load. The load is equally shared between the UPS units.
NOTE: If the transfer conditions are not satisfied (bypass AC input source is out of
tolerance) a forced transfer is required.
Parallel System Shut down from Normal to Maintenance Bypass Operation
CAUTION
HAZARD OF EQUIPMENT DAMAGE
If the inverter outputs are not synchronized with the bypass input, the procedure
will result in a power interruption to the load.
Failure to follow these instructions can result in injury or equipment
damage.
NOTE: If the inverter does not turn off after step 1, proceed to do a forced transfer.

Shut down one UPS Unit in a Parallel System
CAUTION
HAZARD OF EQUIPMENT DAMAGE
Before isolating an individual UPS unit, ensure that the remaining UPS units can
support the load. When one UPS unit is shut down, it may cause an overload or
current-limiting condition if the remaining units are unable to fully support the
connected load. The remaining UPS units may shut down immediately or after a
certain time (depending on the load level), and the load may be transferred to
the bypass source.
Failure to follow these instructions can result in injury or equipment
damage.

Preventive Maintenance
We recommend that preventive maintenance of the EPS 7000 and EPS 8000
Systems is performed twice a year. Your installation and site may require additional
preventive maintenance to ensure optimal performance.
DANGER
HAZARD OF ELECTRIC SHOCK, EXPLOSION OR ARC FLASH
Only qualified personnel must perform preventive maintenance.
Failure to follow these instructions will result in death or serious injury.
Parts Replacement
There are no user-replaceable parts in the EPS 7000 and EPS 8000 Systems.
Three levels of replacement parts are available for the EPS 7000 and EPS 8000
Systems.
Level
Description
A
This level of replacement parts consists of consumable parts,
specifically fuses and air filters. It is recommended to have these
parts on hand during installation of the UPS system, including initial
start-up.
B
This level of replacement parts is recommended when the user can
tolerate short-duration UPS down-time to obtain replacement parts
in the event of a major UPS failure. This level of replacement parts
consists of consumable parts, special fuses, air filters, an inverter
leg, and the most critical circuit board assemblies.
C
This level of replacement parts is recommended when the user can
tolerate only a minimum of down-time in the event of a major UPS
failure. This level of replacement parts consists of consumable
parts, special fuses, air filters, an inverter leg, and a complete set of
circuit board assemblies.
Having replacement parts on hand will prevent any delays (due to time involved in
obtaining spare parts) during critical periods such as system start-up.
Any parts used during start-up will be replaced by Schneider Electric at no charge.
Contact Customer Support for specific recommendations.

Audible Alarms
The following alarm conditions activate the audible alarm:
•
Load transferred to bypass.
•
Load supplied via battery.
•

During minor alarm conditions, the alarm sounds at a slow rate and a low sound
level. When the battery approaches a low-voltage shutdown level, the alarm
sounds louder and at an increased level. If the inverter shuts down, the alarm is
loud and continuous.
Silence the Alarm
1. Open the cover plate to get access to the hidden panel.
