6.3.11 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 UPS
immediately, without asking for verification.
The UPS, 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 6-8).
The rectifier, inverter, battery, and bypass switchgear 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 6-8). To remove the key, rotate the key back to the
vertical position.
3. Restart the UPS by following the procedure in paragraph 6.3.1 or 6.3.2.
WARNING
Power is present inside the UPS cabinet after the upstream input feeder circuit breakers are
opened because of the installed internal batteries.
