NOTE 1 The UPS thermal sensor signal is used to indicate a thermal trip condition and to turn off
the battery charger.
NOTE 2 Disconnect terminal block plug from terminal block to wire plug.
NOTE 3 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.
NOTE 4 Use wire rated for 600V and Class 1 wiring methods.
To install wiring:
1. Verify the UPS system is turned off and all power sources are removed. See
Chapter 7 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 17 for UPS
wiring access information, and Figure 29 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, the Eaton 93PM Integrated Battery Cabinet
Installation Manual-Small, or the Eaton 93PM Integrated Battery Cabinet Installation Manual-Small Welded,
listed in paragraph 1.8 For More Information, 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 15 for UPS wiring access information and
Figure 29 for UPS terminal locations.
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 16 and Figure 17 for UPS wiring access information, and Figure 29 for UPS terminal locations.
10. Connect the wiring to the thermal sensor terminals. See paragraph
3.2.3 UPS System Interface Wiring Preparation and Table 13 for wiring and termination requirements, and
Figure 30 for terminal assignments.
11. Verify jumpers are in position as shown in Figure 31. If jumpers are not installed or are in the incorrect
position, move or install the jumpers as shown in the figure.
12. If wiring generator interface connections, proceed to paragraph 4.7.4 Generator Interface Connections; if
wiring Minislot connections, proceed to paragraph 4.7.5 Installing Minislot Interface Connections;
otherwise, proceed to Step 13.
13. Reinstall all safety shield panels previously removed and secure with the retained hardware.
