180 Eaton Power Xpert 9395 UPS Installation and Operation Manual 164201725—Rev 15
NOTE The following instructions are for the Eaton-supplied REPO switch. If a customer-
supplied REPO switch is used, it may not activate in the same manner; refer to the
operating instructions provided with the switch.
To use the REPO switch:
1. Firmly push the red pushbutton until it locks into place. The switch latches into the activated state (see
Figure 106).
The input, output, and bypass backfeed contactors open, the battery breaker or disconnect is tripped, and
the power module is turned off immediately, without asking for verification.
Do not attempt to restart the system after the REPO until the cause of the shutdown has been identified and
cleared.
2. To deactivate the REPO switch in preparation for restarting the UPS, insert the supplied key and rotate
clockwise until the red pushbutton releases (see Figure 106). To remove the key, rotate the key back to
the vertical position.
3. Restart the UPS by following the procedure in paragraph 7.3.1 Starting the UPS in Online Mode or
7.3.8 Starting the UPS in Bypass Mode.
Power is present inside the UPS cabinet until the upstream input feeder circuit breaker is opened.
