The REPO switch is a customerĆsupplied switch that can disconnect the UPS
output voltage from your protected equipment. The REPO function activates when
the REPO wires are shorted together. Use the following specifications for the
REPO switch:
The switch should be a wallĆmounted, momentaryĆcontact, normally open,
pushbutton switch.
Minimum ratings of 120 VAC and 125 mA.
The REPO wires are at highĆvoltage potential (240V). Refer to your
local electrical code for proper installation of the highĆvoltage REPO wires.
