• Remote emergency power off (REPO) test (if applicable).
• Inverter start and stop (for each module).
• Battery transfer test.
• Maintenance bypass procedure.
This section presents procedures for shutting down the
system under normal, emergency, overload, and
maintenance conditions.
During an emergency situation, such as a fire in the computer or electrical room, the UPS
and all downstream devices can be instantly shut down by pressing the “emergency power off”
(EPO) pushbutton on the front panel of the SSC, or by pressing the “remote emergency
power off” (REPO) optional pushbutton located within the room.
The EPO or REPO pushbuttons should not be used for normal shutdown of the equipment;
when activated, ground paths may be broken (depending on installation) and sensitive loads
attached to the UPS may lose safety ground connection.
Each UPS module has an EPO feature that can be activated to shut down
that module only (see Section 2.2.1).
