UPS Operating Instructions

6-26 Eaton 9E UPS (20–30 kVA, 208/220V) Installation and Operation Manual 164202124—Rev 5 www.eaton.com/powerquality

6.4.15 Using the Remote Emergency Power-off Switch

A UPS emergency power-off is initiated by the REPO pushbutton switch. In an emergency, you can use this

switch to control the UPS output. The REPO switch de-energizes the critical load and powers down the UPSs

immediately, without asking for verification.

The UPSs, including Bypass, remains off until restarted.

CAUTION

All power to the critical load is lost when the REPO switch is activated in the following step. You

should use this feature only when you want to de-energize the critical load.

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 6-9).

The input, output, battery, and bypass backfeed relays open, and the power module is turned off

immediately, without asking for verification.

CAUTION

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 6-9). To remove the key, rotate the key back to the

vertical position.

3. Restart the UPS by following the procedure in paragraph 6.4.1 or 6.4.2.

WARNING

Power is present inside the UPS cabinet after the upstream input feeder circuit breakers are

opened because of the installed internal batteries.

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.
