Routing your Edge® Lightbar Cable(s)
1.
To protect the headliner from damage caused by drilling the
cable access hole through the vehicle roof, allow a 5” to 7”
distance between roof and headliner by lowering the
headliner before drilling.
2.
Using a 1” hole saw, drill the cable access hole.
NOTE:There may be a roof support member that spans the
distance between the driver’s and passenger’s side. DO NOT
DRILL THROUGH THIS MEMBER! Adjust the location until
the hole can be drilled without contacting this support mem-
ber.
3.
Use a round file to smooth and de-burr the edges of the hole.
4.
Insert a 1” grommet (user supplied) into the cable access
hole.
5.
Insert the cable(s) through the cable access hole into the
vehicle. Use RTV silicone to weatherproof the access hole
after the cable(s) are pulled completely into the vehicle.
6.
Route the cable(s) one at a time to their respective
destinations (power cable to vehicle battery; control cable to
customer switch panel). It is left to the installation technician's
discretion to select a path for these cables that will both
protect the cables from possible damage and not interfere
with the operation of any other vehicle components or
equipment. Refer to the instructions included with your
switches for switch wiring information.
NOTE: The outer surfaces of this product may be cleaned
with mild soap and water. Use of any other chemicals may
void product warranty. Do not use a pressure washer.
Connecting the Cables
WARNING! All customer supplied wires that connect to the
positive terminal of the battery must be sized to supply at
least 125% of the maximum operating current and FUSED at
the battery to carry that load. DO NOT USE CIRCUIT
BREAKERS WITH THIS PRODUCT!
Power Cable:
1.
Follow the factory wiring harness through the firewall. It may
be necessary to drill a hole in the firewall. If so, be absolutely
sure that there are no components that could be damaged by
drilling. After the hole has been drilled, insert a grommet to
protect the cable.
2.
Route the cable along the factory wiring harness towards the
battery. Install a 40 amp fuse block (customer supplied) on
the end of the RED wire in the power cable. Remove the fuse
from the fuse block before connecting any wires to the
battery.
3.
Connect the fuse block to the POSITIVE (+) terminal on the
battery. There can not be more than two (2) feet of wire
between the fuse block and the battery. The wire between the
fuse block and the battery is “unprotected”, do not allow this
wire to come into contact with any other wires.
4.
Connect the BLACK wire to the factory chassis ground
adjacent to the battery.
Control Cable:
Extend the control cable to your switch panel and make the
appropriate connections, using the information provided on pages
4 or 5, depending on which lightbar you have. When you apply
+12 VDC to a Control Cable wire, you activate its function. The
control cable connects to your control head or switch box and is
fused there. Typical fusing is 5 Amps.
LowPower / VIOLET :
The type of switch used is dependant on how the operator wishes
the Hi/Low feature to function:
Latching Mode: By applying +12 VDC voltage to the Violet wire
for less than 1 sec., the power supply is “latched” into low power
operation. The unit must be turned off and then back on to restore
normal, Hi power operation. (A Momentary Switch is Preferred)
Level Mode: Applying +12 VDC voltage to the Violet wire for
more than 1 sec. holds the power supply in low power mode until
voltage is removed. (A Toggle Switch is Preferred)
NOTE: The wire functions listed in this manual are the factory
default settings for a fully loaded lightbar. To find the correct
wire functions for the lightbar you ordered, refer to the
switch operations sheet included with your lightbar.
Troubleshooting:
Your lightbar should now be fully operational. If your lightbar is not
functioning properly, check the following:
•
The positive wire (RED) is properly connected to the
battery, by way of the user supplied fuse block.
•
A working fuse of the correct amperage (40 amp) is
installed in the fuse block.
•
The ground wire (BLACK) is properly connected to the
factory ground.
If these connections are good, contact your Whelen
representative for further assistance.
