Connecting the System
Note:
• This unit is for vehicles with a 12-volt battery
and negative grounding. Before installing it in a
recreational vehicle, truck, or bus, check the bat-
tery voltage.
• To avoid shorts in the electrical system, be sure
to disconnect the ≠ battery cable before begin-
ning installation.
• Refer to the owner’s manual for details on con-
necting other units, then make connections cor-
rectly.
• Secure the wiring with cable clamps or adhesive
tape. To protect the wiring, wrap adhesive tape
around them where they lie against metal parts.
• Route and secure all wiring so it cannot touch
any moving parts, such as the gear shift, hand-
brake and seat rails. Do not route wiring in
places that get hot, such as near the heater outlet.
If the insulation of the wiring melts or gets torn,
there is a danger of the wiring short-circuiting to
the vehicle body.
• Don’t pass the yellow lead through a hole into
the engine compartment to connect to the battery.
This will damage the lead insulation and cause a
very dangerous short.
• Do not shorten any leads. If you do, the protec-
tion circuit may fail to work when it should.
• Never feed power to other equipment by cutting
the insulation of the power supply lead of the
unit and tapping into the lead. The current capac-
ity of the lead will be exceeded, causing over-
heating.
• When replacing a fuse, be sure to use only fuses
of the rating prescribed on the fuse holder.
• If this unit is installed in a vehicle that does not
have an ACC (accessory) position on the ignition
switch, the red lead of the unit should be con-
nected to a terminal coupled with ignition switch
ON/OFF operations. If this is not done, the vehi-
cle battery may be drained when you are away
from the vehicle for several hours.
