Models VSLR1 and VSLR1-IPX
7.
Install one or two mounting pads over each of the three mounting studs as shown in Figure 1.
8.
Position the light over the mounting holes and route the cable through the grommet. For the VSLR1-IPX,
allow 10
"
to 18
"
of slack in the cable under the roof so the unit can be removed if the Impaxx is damaged
and needs replacement.
9.
To prevent water leakage if applicable, apply a silicone sealing compound around the cable and
grommet where they pass through the mounting surface.
10.
Secure the unit to the mounting surface with the three 1/4
"
-20 elastic stop nuts.
Wiring the Light in the Vehicle
The light is completely wired at the factory and does not require any additional internal wiring. All the
conductors necessary for control of light assembly are contained in the leads. The basic light functions of
the unit must be controlled by a installer-supplied control head. Before proceeding, ensure that the light
assembly has been installed on the vehicle roof in accordance with the instructions
LOCATION OF LIGHT SYSTEM CONTROLS—Locate the light system controls so the
VEHICLE and CONTROLS can be operated safely under all driving conditions.
To wire the light assembly:
1.
Determine the length of wires needed for the installation. For lengths up to 15 ft (5 m), use minimum
18 AWG (1 mm
2
) wire. For lengths over 15 ft, use minimum 16 AWG (1.5 mm
2
) wire.
Use insulated butt connectors to splice the leads. Ensure that the connectors are securely crimped and
properly insulated.

. See Figure 3 on page 5. Connect the black lead to chassis ground (
–
NEG).
3.
Connect the red wire (+BAT) to one terminal of an installer-supplied switch with a current capacity of at
least 8 A.
4.
Connect the other terminal of the switch through an installer-supplied 8 A fuseholder to the positive
(+BAT) terminal of the voltage source.
