4.6 Installing a REPO Switch
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. Shows a
REPO switc h.
NOTE 1
Before installing a REPO
switch, verify that the UPS was installed according to the
instructions in paragraphs 4.2 through 4.5.
NOTE 2
When installi
ng the REPO
switch, you must install conduit between the device and
the UPS cabinet for wiring the switc h.
NOTE 3
The REPO
switch must be a normally-open or normally-closed latching-type switc h
not tied into any other circuits.
NOTE 4
This
procedure is intended for installing the Eaton-supplied REPO switch. If
installing
another manufacturer's switch, use this procedure, and Figure 4-13 and
Figure 4-14 as a guide.
To Install a
REPO
switc h:
The REPO switch wiring must be in accordance with local regulations
1. V erify t he UPS system is turned off and all power sources are removed. See Chapter 6, “UPS Operating
Instructions,“ for shutdown instr uctions.
2. Securely mount the REPO switch. Recommended locations include operator's consoles or near exit doors.
3. To locate the appropriate terminals and review the wiring and termination requirements, see
paragraph 3.2.3, Table 4-3, Figure 4-5, Figure 4-6, and Figure 4-1 1.
