HP R5500 manual ERM rear panel

The REPO feature shuts down UPS units operating under either utility or battery power.

NOTE: If the UPS was operating on battery power when the remote switch was closed, no power is available to the load devices until utility power is restored and the UPS has been manually powered up.

To restore power to the load devices after the REPO feature is activated, press the On button after the AC source is reconnected to the UPS.

IMPORTANT: Pressing and holding the On button without utility present normally initiates a battery start and the UPS assumes the load. However, if the On button is pressed and a REPO is detected, battery start is inhibited and the UPS is not able to assume the load. The electronics module fan spins and the General Alarm LED and an audible alarm are active as long as the On button is held.

To power down the entire network in the event of an emergency, the REPO ports of multiple UPS units can be connected to a single switch.
