Eaton Power Xpert 9395P UPS (300 kVA, 300 kW) Installation and Operation Manual
A latching-type Remote Emergency Power-off (REPO) switch can be used in an
emergency to shut down the UPS and remove power to the critical load from a
location away from where the UPS is installed. Figure 4‐17 shows a REPO switch.
NOTE Before installing a REPO switch, verify that the UPS was installed according to the instructions in
paragraphs 4.2 through 4.7.
NOTE When installing the REPO switch, you must install conduit between the device and the UPS cabinet
for wiring the switch.
NOTE Remove the UPS cabinet interface entry conduit landing plates to drill or punch holes
(see Figure 4‐5).
NOTE The REPO switch must be a normally-open or normally-closed latching‐type switch not tied into any
other circuits.
NOTE 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.
NOTE The REPO switch wiring must be in accordance with NEC Article 725 Class 2 requirements.
To Install a REPO switch:
1.
Verify the UPS system is turned off and all power sources are removed. See
Chapter 7, "UPS Operating Instructions," for shutdown instructions.
2.
Securely mount the REPO switch. Recommended locations include operator's
consoles or near exit doors. See Figure 4‐16 for enclosure dimensions and wiring
knockouts.
