the cables run into the control box. There is a bushing provided if the cable outer diameter does
not match the cable grip diameter to install if needed. Refer to the wiring diagram WD-43437
contained in the Appendix section. Be sure to follow the recommended torque requirements
found in the wiring diagram. Remove the screws on the control box lid and open the lid to expose
the base board mounted to the back of the lid.
5.10.1
Wiring Remote Control Cable to the Base Board
The bulkhead cable (or PMRC Control Cable) connects the bulkhead, remote control, and base
board. Route the cable through the cable grip labeled HHRC in Figure 5-11. Then connect the
wires from the bulkhead cable (or PMRC Control Cable) to the green J4 connector located on the
top left of the base board, ensuring the wires match the color strip on the J4 connector and the
wiring diagram. Connect the J4 connector to the base board.
5.10.2
Wiring Magnetic Switches to the Base Board
The cables for the upper and lower magnetic switches installed on the mast can be routed
through one of the cable grips. These cables may need to be extended, depending on the
location of the control box.
Connect the magnetic limit switch wires to the connector supplied for J3, ensuring the wires
match the wiring diagram. Connect the J3 connector to the base board.
5.10.3
Wiring DC Source Power to the Mast Control Circuit
The mast control system requires DC power regardless of what power is required by the lighting
circuits (AC or DC). Source DC power is provided by the installer from the vehicle battery. The
mast system will operate with 12VDC or 24VDC source power.
The base board contains a 20 amp fuse to protect the mast control circuits from over-current
events. The installer is responsible for providing the means to remove/isolate power from the
mast and permit the operator to follow proper lock-out tag-out procedures for maintenance or
troubleshooting.
Route the DC power cable into the control box. Attach the 0.709 inch (18 mm) inside diameter
ferrite (shipped loose with the mast) around the Control/DC cable as it enters the control box.
This ferrite provides electromagnetic interference (EMI) filtering.
Power cables for the mast controls are provided by the installer. The cables must:
• Be type SJOOW or equivalent
• Be 10 AWG (or 6 mm
2
) conductors
• Have a maximum length for acceptable voltage drop of 70 feet (21 meters)
