4.11.2 Installing Battery Detect Interface Connections

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 wiring the battery detect connections using the inter-cabinet wiring access pass-through
(line-up-and-match configurations), proceed to Step 4; if wiring the battery interface connections using
bottom entry access, proceed to Step 6; if wiring the battery interface connections using top entry
access, proceed to Step 12.
4. Pass-through Wiring. Route the battery detect wiring from the battery cabinet through the top UPS
inter-cabinet wiring access pass-through to the UPS building alarm terminals. See Figure 4-6 for UPS
wiring access information, and Figure 4-9 and Figure 4-10 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-Small
Welded IBC-SW (432V and 480V) Installation Manual, listed in paragraph 1.8, for battery cabinet wiring
access information and instructions.

NOTE 2 Any pair of unused building alarm terminals may be used for the battery detect
connections.
NOTE 3 Program the battery detect building alarm to read battery open and for normally
open contacts.
NOTE 4 If installing interface wiring connections between standalone cabinets, conduit
must be installed between cabinets.
