NOTE
Before installing a REPO switch, verify that the PDU was installed according to the instructions in
Chapter 3, Installing the PDU."
NOTE
When installing the REPO switch, you must install conduit between the device and the PDU cabinet
for wiring the switch.
NOTE
The REPO switch must be a normally−open or normally−closed latching-type switch not tied into any
other circuits. The factory default configuration is set up for use with a normally−open switch. To use a
normally−closed switch, the configuration must be changed during setup by an Eaton Customer Service
Engineer

NOTE
This procedure is intended to be used for the installation of the Eaton REPO switch. If installing
another manufacturer’s switch, use this procedure only as a guide.
NOTE
The REPO switch wiring must be in accordance with NEC
®
