NOTE
Batteries and heater pads in the Power Cabinet MUST be
installed in the bottom slots of the battery compartments

power cables are "daisy–chained" from the bottom in each
battery compartment (see Figure 4-7). The last (top) heater
pad cable must be terminated with a connector that is
shipped installed on the cable located in the bottom slot of
each battery compartment (positions 1 and 2).

ALL heater pads should be installed and cables properly
dressed before ANY batteries are installed.
