4.8 Installing a
R
EPO switch
NOTE
Before installing a REPO switch, verify that the UPS was installed according to the instructions
in paragraphs 4.2 through 4.7.
When installing the REPO switch, you must install conduit between the device and the UPS
cabinet for wiring the switch.
Remove the UPS cabinet interface entry conduit landing plates to drill or punch holes (see
Figure
4‐4).
The REPO switch must be a normally-open or normally-closed
latching‐type
switch not tied
into any other circuits.
This procedure is intended to be used for the installation of the Eaton-supplied REPO switch. If
installing another manufacturer's switch, use this procedure only as a guide.
The REPO switch wiring must be in accordance with NEC Article 725 Class 2 requirements.
A latching-type Remote Emergency Power-off (REPO) switch can be used in an emergency to shut
down the U
PS
and remove power to the critical load from a location away from where the UPS is
installed. Figure 4
