10-40 kVA 400 V & 10-20 kVA 208 V 3:3,10-30 kVA 400 V 3:1 Operation Modes
Operation Modes
Normal Mode
The UPS provides power to the connected load from mains. The UPS converts
mains to conditioned power for the connected load while recharging the batteries
(float or boost charge).
LED Status Power Flow
Battery Mode
The UPS transfers to battery mode if the mains supply fails. The UPS provides
power to the connected load from the connected batteries for a finite period. When
the mains supply returns, the UPS transfers back to normal mode.
LED Status Power Flow
Static Bypass Mode
The UPS supplies the load with power from the bypass source. If the conditions
for normal or battery mode are not met, the load will be transferred from the
inverter to the bypass source with no interruption in power to the load.
20 990-91079F-001
Operation Modes 10-40 kVA 400 V & 10-20 kVA 208 V 3:3,10-30 kVA 400 V 3:1
LED Status Power Flow
Maintenance Bypass Mode
In maintenance bypass mode, the mains is sent via the (external) maintenance
bypass breaker (MBB) to the load. Battery backup is not available in maintenance
bypass mode.
LED Status Power Flow
ECO Mode
In ECO mode the UPS is configured to use static bypass mode as the preferred
operation mode under predefined circumstances. The inverter is in standby in
ECO mode and in case of interruption to the mains, the UPS transfers to battery
mode and the load is supplied from the inverter.

10-40 kVA 400 V & 10-20 kVA 208 V 3:3,10-30 kVA 400 V 3:1 Operation Modes
LED Status Power Flow
Autostart Mode
The batteries will reach end of discharge if the interruption to the mains is longer
than the battery runtime. If the UPS is programmed to auto-restart after end of
discharge, the system will automatically restart after a delay when the mains
returns.
NOTE: If autostart is disabled, the inverter and bypass will not restart
automatically when the mains return.
Frequency Converter Mode
In frequency converter mode, the UPS presents a stable output frequency (at 50
or 60 Hz) and the static bypass switch is not available.
NOTICE
RISK OF EQUIPMENT DAMAGE OR LOAD DROP
In frequency converter mode the UPS cannot run in static bypass or
maintenance bypass mode. Before turning the UPS into frequency converter
mode, you must contact a Schneider Electric-certified partner to make sure
• the static switch input breaker SSIB and the maintenance bypass breaker
MBB are in the OFF (opened) position (Schneider Electric strongly
recommends to lock these with a padlock available from Schneider Electric)
• no cables are connected to the bypass terminals
Failure to follow these instructions can result in equipment damage.
NOTICE
RISK OF LOAD DROP
When the unit output breaker UOB is opened while the UPS is in frequency
converter mode, the load will not be transferred, but will be dropped.
Failure to follow these instructions can result in equipment damage.

DANGER
HAZARD OF ELECTRICAL SHOCK, EXPLOSION OR ARC FLASH
• Wait at least 5 minutes before removing the cover of the UPS after the
display has turned off to allow for the capacitors to fully discharged.
• Always measure for hazardous voltages on all terminals before working
on the UPS.
Failure to follow these instructions will result in death or serious
injury.
Start Up and Add a UPS to a Running Parallel System
Use this procedure to start up a UPS and add it to a running parallel system.
IMPORTANT: Before a UPS can be added to a parallel system, the parallel
system must be configured by Schneider Electric.
1. On the new UPS check that:
• all UPS breakers (unit input breaker UIB, static switch input breaker
SSIB, and unit output breaker UOB) and the external unit output breaker
Ext. UOB are in the ON (closed) position
• the battery breaker(s) BB are in the OFF (open) position
2. Turn the external unit output breaker Ext. UOB of the UPS to the ON (closed)
position.

Tests
Perform a Battery Maintenance Test
Prerequisite:
• The bypass supply must be within specifications.
• The battery capacity must be above 25%.
The battery maintenance test is used to test the condition of the batteries.
During the battery maintenance test, the system transfers to battery mode and
discharges the batteries until the battery low voltage alarm is reached.
1. On the display, select and then select Maint test.
NOTE: If you wish to manually stop the battery test, select Stop test.
If the battery maintenance test is passed, Battery maintenance OK will be
recorded in the log. If the battery maintenance test is not passed, Batt maint
incomplete will be recorded in the log.
Perform a Battery Test
The purpose of the battery test to verify the connection of the batteries and to
check the battery capacity.
Prerequisite:
• The bypass supply must be within specifications.
• The battery capacity must be above 25%.
• The battery voltage must be above 95% of the float voltage.
During the battery test, the system transfers to battery mode for approximately 30
seconds and then returns to normal mode.
1. On the display, select and then select Battery test.

Maintenance
Parts Replacement
Determine if you need a Replacement Part
To determine if you need a replacement part, contact Schneider Electric and
follow the procedure below so that the representative can assist you promptly:
1. In the event of an alarm condition, scroll through the alarm lists, record the
information, and provide it to the representative.
2. Write down the serial number of the unit so that you will have it easily
accessible when you contact Schneider Electric.
3. If possible, call Schneider Electric from a telephone that is within reach of the
display so that you can gather and report additional information to the
representative.
4. Be prepared to provide a detailed description of the problem. A representative
will help you solve the problem over the telephone, if possible, or will assign a
return material authorization (RMA) number to you. If a module is returned to
Schneider Electric, this RMA number must be clearly printed on the outside of
the package.
5. If the unit is within the warranty period and has been started up by Schneider
Electric, repairs or replacements will be performed free of charge. If it is not
within the warranty period, there will be a charge.
6. If the unit is covered by a Schneider Electric service contract, have the
contract available to provide information to the representative.
Replace the Dust Filter
1. Lift the front panel free of the UPS cabinet.
NOTE: Be careful not to disconnect the cable on the rear side of the front
panel.
