3.2.8Emergency Power Off
The Remote Emergency Power Off (REPO) mode is used to remove all power from the critical load.
The Remote Emergency Power Off control is a switch located remotely from the UPS system. It will normally be in the same room as the critical load equipment. This mode can also be initiated by an automatic contact closure in the same external circuit as the manually operated switch.
When you operate the Emergency Power Off switch, all UPS circuit breakers are opened including the bypass circuit breaker. All power through the UPS is removed from the load. Typically, the REPO circuit also opens the circuit breakers that provide power to the bypass lines and the UPS controls.
Refer to 3.3.3 - Shutdown Procedures.
