You are now ready to connect the battery cables. Make sure the truck battery posts are clean, as
improper connections could cause the APU to fail. Always be careful not to reverse polarity of the battery
cables or touch the positive cable to ground. Doing so will cause detrimental damage to APU, and possibly
the truck, and is also a fire hazard.
Route both positive and negative battery cable from
the APU to the truck's battery bank. Zip tie all slack
during this process.
Be extra careful to not let the cables rest on or come in
contact with any moving parts. This could cause a short
in the future.
Once inside the battery compartment, trim all excess
so that the connectors will fit properly.
Connect the ground (black) wire to the negative battery
post. Do not connect this to a frame or any other
metal for ground.
Prior to connecting the positive cable to the
batteries, install the included MRBF fuse onto one of
the positive posts on the battery. This will be the APU
power supply and truck charge supply. This fuse is
necessary to protect against any potential electrical
hazards.
Install the fuse holder to the positive terminal of the
battery.
The MRBF fuse will slide over the fuse holder post followed
by the positive cable from the APU. It is
then to be secured with the supplied self locking nut.
Place the red cap over the exposed fuse holder post to
prevent a possible arc hazard.
Heavy sparking indicates a system short. Do not continue if either post
sparks. Instead, check the integrity of the cable and whether or not
reverse polarity has occurred.
IMPORTANT
Before connecting the battery cables, make sure that the APU
commander is not plugged in. The Commander should be the last thing
that is connected before the unit is to be started.
