NOTE: The following instructions are for the Eaton-supplied remote
EPO switch. If a customer-supplied remote EPO switch is used, it may
not activate in the same manner. Refer to the operating instructions
provided with the switch.
To use the remote EPO switch:
1.
Firmly push the red pushbutton until it locks into place. The switch
latches into the activated state.
The input, output and battery relay and the optional bypass
backfeed contactor open, and the power module is turned off
immediately, without asking for verification.
CAUTION
Do not attempt to restart the system after the remote EPO until the
cause of the shutdown has been identified and cleared.
2.
To deactivate the remote EPO switch in preparation for restarting
the UPS, insert the supplied key and rotate clockwise until the red
pushbutton releases. To remove the key, rotate the key back to the
vertical position.
3.
Restart the UPS by following the procedure in Section 7.4.1 or
7.4.1.
WARNING
Power is present inside the UPS cabinet after the upstream input
feeder circuit breakers are opened because of the installed external
battery cabinet.
