2.
Prepare earth ground cable entry hole.
If not already per
formed, remove a grommet for the earth ground cable
entry and install any fitting, adapter or grommet in the
hole, per company practice. See Paragraph 3.5.1 through
3.5.3 for more details.
3.
Route earth ground wire to main Boxer cabinet ground
plate.
Run an earth ground cable (#6 to #14 gauge wire )
into the main Boxer cabinet, up through the prepared
knock‐out in the floor of the main cabinet, and over to the
ground lug installed on the ground plate of the main Boxer
cabinet.
4.
Seal the earth ground entrance hole.
Depending on the
type of fitting or grommet used, it may be necessary to seal
the ground wire entrance hole, as stated in the note below.
‐ NOTE ‐
To improve the integrity of the cable entry seals when rubber
grommets are used, a water‐proof foam or silicone sealant
should be used on the interior side of the cabinet, around the ex
posed grommet and cable entry.

Making Battery Connections
To make battery connections in the battery box, a battery heat
er pad (optional), the batteries, a battery tie‐down strap, and
battery cable must be installed. The paragraphs below provide
a description of these procedures.
3.7.1
Installing an Optional Heater Pad
A optional battery heater pad, Model BXA05V‐HP2, if
ordered, should be installed in the battery box prior to mount
ing the batteries. Unpack and unroll the heater pad. Place the
heater pad on the floor of the battery compartment
(Figure 18), connector cable side up, and connector end near
the right wall. Spread out the pad to cover the entire compart
ment floor. Connect the heater pad's connector to the battery
cable (Connector C in Figure 17) in Paragraph 3.7.2 after the
battery cable is installed.
3.7.2
Installing the Battery Cable
A special battery cable (Figure 17) is shipped with the battery
box, to facilitate backup battery connections. The battery end
of this cable contains 4 connectors (shown as connectors A, B,
C, D in Figure 17), which are connected to the batteries and the
battery heater pad in the battery box. The power end of the
cable also contains 4 connectors (shown as connectors E, F, G,
and H in Figure 17), which are connected to AC and DC power
connectors in the main cabinet
above
the battery box. The
middle of the cable contains a special grommet (fitting with a
threaded coupler and lock nut) which is installed in the hole at
the bottom of the Boxer main cabinet. Follow the steps below
to connect the battery cable.
1.
Locate battery cable.
Find the battery cable located inside
the bag of parts shipped with the battery box, and remove
