If required, install ½

conduit and wiring from the second contact block in the
REPO station to trip circuitry of other equipment, such as upstream protective
devices, facility monitoring devices, or alarms. Using the contact block that was
not used for the UPS EPO wiring will help maintain isolation between the control
systems.
A normally open (NO) contact and a normally closed (NC) contact are provided,
and the two are electrically isolated. If single−pole, double−throw action is desired,
one side of the NO contact can be jumpered to one side of the NC contact to
form the common connection point. REPO switch wiring must be according to
UL Class I requirements.

When all wiring is complete, close the inside distribution panel doors and secure
with screws.

Close the outside doors and secure the latch.
