Unpacking & Pre-Installation
Carefully remove the lightbar and place it on a fl at surface, taking care not to scratch the lenses or damage the cable coming out of
the bottom. Examine the unit for transit damage, broken lamps, etc. Report any damage to the carrier and keep the shipping carton.
Standard lightbars are built to operate on 12 volt D.C. negative ground (earth) vehicles. If you have an electrical system other than 12
volt D.C. negative ground (earth), and have not ordered a specially wired lightbar, contact the factory for instructions.
Test the unit before installation. To test, touch the black wire to the ground (earth) and the other wires to +12 volts D.C., in accordance
with the instructions attached to the cable (an automotive battery is preferable for this test). A battery charger may be used, but please
note that some electronic options (fl ashers, etc.) may not operate normally when powered by a battery charger. If problems occur at
this point, contact the factory.
Installation & Mounting
MOUNTING HARDWARE - Mounting hardware is usually packed in a small box inside the main carton although some mounting kits
may be shipped separately. Refer to the Installation Manual included in the mounting kit for mounting instructions. Note: Hook-on
mounting for "gutterless" type vehicles will require a special hook for mounting. Several special application hooks are avail-
able. Contact the factory for details.
Utilizing non-factory supplied screws and/or mounting brackets and/or the improper number
of screws may result in loss of warranty coverage on the equipment.
Wiring Instructions
Larger wires and tight connections will provide longer service life for components. For high current wires it
is highly recommended that terminal blocks or soldered connections be used with shrink tubing to protect
the connections. Do not use insulation displacement connectors (e.g. 3M
® Scotchlock type connectors).
Route wiring using grommets and sealant when passing through compartment walls. Minimize the number
of splices to reduce voltage drop. High ambient temperatures (e.g. underhood) will signifi cantly reduce the
current carrying capacity of wires, fuses, and circuit breakers. Use "SXL" type wire in engine compartment.
All wiring should conform to the minimum wire size and other recommendations of the manufacturer and
be protected from moving parts and hot surfaces. Looms, grommets, cable ties, and similar installation
hardware should be used to anchor and protect all wiring. Fuses or circuit breakers should be located as
close to the power takeoff points as possible and properly sized to protect the wiring and devices. Particular
attention should be paid to the location and method of making electrical connections and splices to protect
these points from corrosion and loss of conductivity. Ground terminations should only be made to sub-
stantial chassis components, preferably directly to the vehicle battery. The user should install a fuse sized
to approximately 125% of the maximum Amp capacity in the supply line to protect against short circuits.
For example, a 30 Amp fuse should carry a maximum of 24 Amps. DO NOT USE 1/4" DIAMETER GLASS
FUSES AS THEY ARE NOT SUITABLE FOR CONTINUOUS DUTY IN SIZES ABOVE 15 AMPS. Circuit
breakers are very sensitive to high temperatures and will "false trip" when mounted in hot environments or
operated close to their capacity.
Before attempting to connect wiring, refer to wire tag attached to the lightbar's main cable. Each wire in the cable controls a
separate lightbar function as described in the wire tag.
Route the wiring cable into the engine or passenger compartment, taking care to use grommets and to apply sealant around
openings to keep water out. It is advisable to leave an extra loop of cable when installing the lightbar to allow for future changes
or reinstallations. Connect the black lead to a solid frame ground (earth), preferably, the (-) or ground (earth) side of the battery
and bring the other wires to the control head or switches. Connect the wires as directed by the wiring instructions on the cable.
