Step
n WARNING
1
Ensure battery heater circuit breakers in ACLC are "OFF" before heater pad
installation.
Remove the battery mounting bracket (see Figure 4-6) for the appropriate battery slot.
2 If this is the first heater pad installed in the battery cabinet (and therefore located in
one of the two bottom battery slots) remove the "Heater Pad Cable Terminating
Connector" from the end of the factory installed cable in the bracket at the back of the
bottom slot of the battery compartment (see Figure 4-7).
* IMPORTANT
Save this terminating connector, it must be used to terminate the cable of the last
heater pad in the battery compartment.
3 Remove the adhesive liners, and slide the heater pad into the slot, ensuring proper
orientation (see Figure 4-4) and that the heater pad rests flat on the battery shelf with
the cable to the rear.
4 Connect the short heater pad cable to either:
* IMPORTANT
Verify that the connector latches engage (there should be an audible "click") when
connecting cables.
5 If the heater pad is the last (top) in the series of heater pads (and therefore does not
have a heater pad above it), terminate the long cable with the terminating connector
removed from the factory installed cable in step 2.
6 Repeat this procedure until all heater pads are installed, then proceed to the battery
installation.

Table 4-5: Installing a Battery Heater Pad
– The cable (factory installed) to the bracket in the back of the bottom slot, if the
heater pad is in position 1 or 2 (see Figure 4-6 and Figure 4-7).
– The long cable of the heater pad in the slot below, if the heater pad is not the first
in the compartment (see Figure 4-7).
*
After all of the heater pads have been installed and cables
connected, dress the cables behind the battery shelves in
each battery compartment. When dressing cables,
consideration should be given to future accessibility of the
cables should a heater ever need to be replaced. Do not zip
tie cables to battery shelves or each other. Also, do not
tangle cables in one another. Ensure cables are routed such
that a heater pad cable connector for one shelf can be
pulled up from the shelf below it without having to remove
the batteries below.
