NOTE 1
NOTE 2
NOTE 3
NOTE 4
To install wiring:
1.
Verify the UPS system is turned off and all power sources are removed. See Chapter 6, "UPS Operating
Instructions, " for shutdown instructions.
2.
If not already opened, open the front door by lifting the latch from the bottom and turning to the right
(counterclockwise) and swing the door open.
3.
If not already removed, remove the screws securing the lower internal safety shield panel and remove the
panel. Retain the hardware for later use.
4.
If wiring the thermal sensor connections using the inter-cabinet wiring access pass-through
(line-up-and-match configurations), proceed to Step 5; if wiring the thermal sensor connections using
bottom entry access, proceed to Step 7; if wiring the thermal sensor connections using top entry access,
proceed to Step 9.
5.
Pass-through Wiring. Route the thermal sensor wiring from the battery cabinet through the bottom UPS
inter-cabinet wiring access pass-through to the UPS thermal sensor terminals. See Figure 4-6 for UPS
wiring access information, and Figure 4-18 for UPS terminal locations. Refer to the Eaton 93PM Integrated
Battery Cabinet Installation Manual-Large and Large High Rate, the Eaton 93PM Universal Integrated
Battery Cabinet Installation Manual-Large and Large High Rate, or the Eaton 93PM Integrated Battery
Cabinet Installation Manual-Small, listed in paragraph 1.8, for battery cabinet wiring access information
and instructions.
6.
Proceed to Step 10.
7 .
Bottom Entry Wiring. Route the thermal sensor wiring from the battery cabinet through the bottom of
the UPS to the UPS thermal sensor terminals. See Figure 4-4 for UPS wiring access information and
Figure 4-18 for UPS terminal locations. Refer to the Eaton 93PM Integrated Battery Cabinet Installation
Manual-Large and Large High Rate, the Eaton 93PM Universal Integrated Battery Cabinet Installation
Manual-Large and Large High Rate, or the Eaton 93PM Integrated Battery Cabinet Installation
Manual-Small, listed in paragraph 1.8, for battery cabinet wiring access information and instructions.
8.
Proceed to Step 10.
9.
Top Entry Wiring. Route the thermal sensor wiring from the battery cabinet through the top of the UPS
sidecar and the bottom UPS inter-cabinet wiring access pass-through to the UPS thermal sensor
terminals. See Figure 4-5 and Figure 4-6 for UPS wiring access information, and Figure 4-18 for UPS
terminal locations. Refer to the Eaton 93PM Integrated Battery Cabinet Installation Manual-Large and
Large High Rate, the Eaton 93PM Universal Integrated Battery Cabinet Installation Manual-Large and
Large High Rate, or the Eaton 93PM Integrated Battery Cabinet Installation Manual-Small, listed in
paragraph 1.8, for battery cabinet wiring access information and instructions.
10. Connect the wiring to the thermal sensor terminals. See paragraph 3.2.4 and Table 4-4 for wiring and
termination requirements, and Figure 4-19 for terminal assignments.
11. Verify jumpers are in position as shown in Figure 4-20. If jumpers are not installed or are in the incorrect
position, move or install the jumpers as shown in the figure.

Eaton 93PM UPS (20–50 kW, 480V Four Wire – 50 kW Frame) Installation and Operation Manual P-164000540—Rev 4
The UPS thermal sensor signal is used to indicate a thermal trip condition and to
turn off the battery charger.
Disconnect terminal block plug from terminal block to wire plug.
If the inter-cabinet wiring access pass-through is not used to install the thermal
sensor interface wiring connections, conduit must be installed between the battery
cabinet and the UPS cabinet.
Use wire rated for 600V and Class 1 wiring methods.
