Remote Emergency Power-Off

The Powerware 9125 includes a REPO port that allows power to be

remains in Standby mode when restarted until the On button is
pressed.

the input power must be disconnected from the UPS when the emergency power-off
function is activated.
NOTE The REPO function activates when the REPO contacts open.
NOTE If the REPO function is not needed, the REPO connector must remain installed
in the REPO port on the UPS rear panel.
