Installing Thermal Sensor Interface Connections
1.
If wiring the IBC–SW thermal sensor interface terminals using line-up-and-match wiring using the
inter-cabinet wiring access pass-through (see Figure 4-2) proceed to Step 2; if wiring the IBC–SW thermal
sensor interface terminals using the top entry access, proceed to Step 4; if wiring the IBC–SW thermal
sensor interface terminals using the bottom entry access, proceed to Step 7.
2.
Line-Up-and-Match Wiring.
Route the thermal sensor interface wiring from the UPS thermal sensor
(building alarm) interface terminals through the top inter-cabinet access pass-through (see Figure 4-2) of
the UPS cabinet and IBC–SW to the IBC–SW battery interface terminal block TB2. See Figure 4-10 for
terminal locations. See paragraph 3.2.3, Table 4-1, and Figure 4-11 for wiring and termination
requirements. Refer to the applicable Eaton 93PM UPS Installation and Operation manual listed in
paragraph 1.7, for UPS cabinet terminal locations.
3.
Proceed to Step 10.
4.
Top Entry Wiring.
Remove the top conduit plate (see Figure 4-9) from the top of the IBC–SW. Identify all
conduit requirements and mark their location. Drill and punch all conduit holes in the top conduit plate
prior to mounting on the IBC–SW. Install the conduit plate and install all conduit runs into the plate. Pull
the wiring through the conduit into the wiring area.
5.
Route the thermal sensor interface wiring from the UPS thermal sensor (building alarm) interface
terminals through the top of the IBC–SW and the top IBC–SW inter-cabinet wiring access pass-through
(see Figure 4-2) to the IBC–SW battery interface terminal block TB2. See Figure 4-10 for terminal
locations. See paragraph 3.2.3, Table 4-1, and Figure 4-11 for wiring and termination requirements. Refer
to the applicable Eaton 93PM UPS Installation and Operation manual listed in paragraph 1.7, for UPS
cabinet terminal locations.
6.
Proceed to Step 10.
7.
Bottom Entry Wiring.
Remove the bottom conduit plate (see Figure 4-9) from the inside bottom of the
IBC–SW. Identify all conduit requirements and mark their location. Drill and punch all conduit holes in the
bottom conduit plate prior to mounting on the IBC–SW. Install the conduit plate and install all conduit runs
into the plate. Pull the wiring through the conduit into the wiring areas.
NOTE 1
The UPS thermal sensor signal uses an UPS building alarm input to indicate a
thermal trip condition and to turn off the battery charger.
NOTE 2
Any pair of unused building alarm terminals may be used for the thermal sensor
connections.
NOTE 3
Program the thermal sensor building alarm to read battery thermal trip and for
normally open contacts.
NOTE 4
Disconnect terminal block plug from terminal block to wire plug.
NOTE 5
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
In multiple IBC–SW installations, route the battery interface wiring between
IBC–SWs through the top of the adjacent IBC–SW using the top inter-cabinet
access pass-through (see Figure 4-2 on page 4-5).
