NIGHT SCAN POWERLITE, POWERLITE XTREME, AND POWERLITE HDT
2. If 12 VDC lights, because of the higher current draw, line drop from the source to the unit may
be a problem. The user should calculate the line drop for the lights used based on the cable
size/length of run. The lights need 12 VDC minimum at the board under all expected
operating conditions. It is recommended that two separate 12 VDC power feeds be run to the
base board (four wires total). For lower total wattage lights kits, one ± pair of 12 VDC lines
connect to the bottom (RIGHT POWER) on TB1 terminal block. The other ± pair of 12 VDC
lines connect to the top (LEFT POWER) of TB2 terminal block. Note: 10-gauge max.
3. For higher total wattage light packages, connect four 8-gauge DC cables to the terminal block
mounted to the Look-Up light. The connection to the system is pre-wired at the factory.
4. Secure all loose wires with wire ties.
5. Attach the 0.709" inside diameter ferrite (shipped with the mast) around the Control/DC cable
as it enters the base. This ferrite provides EMI (electromagnetic interference) filtering.
6. Replace the base cover.
Light power cables can be purchased from The Will-Burt Company or provided by the installer.
For CE conformity, the installer must provide the light power cables in conformance with
applicable Directives. Cables supplied by The Will-Burt Company do not have blue color for
conductor identification.
If the cables are supplied by the installer, the cables must:
Condition #1: 120/240 VAC, 24 VDC and 12 VDC (with current ≤ 20 Amps per circuit)
• Be type SOOW or equivalent
• Be 10 AWG (or 6mm
• Have a maximum length for acceptable voltage drop of 70 feet (21 meters)
Condition #2: 12 VDC with current > 20 Amps per circuit using added solenoid
• Be type SOOW or equivalent
• Be 8 AWG (or 10mm
• Have a maximum length for acceptable voltage drop of 30 feet (9 meters)
For Condition #1 there are two inputs on the right side of the Base Board for attaching the light
power conductors.
7. Connect the light power to TB1 terminal block (RIGHT POWER) and TB2 terminal block
(LEFT POWER) following the polarity labeled on the Base Board. For AC lights, connect the
ground to the ground bar mounted on the base below the Base Board.
