• Be 10 AWG (or 6 mm
2
) conductors.
• Have a maximum length for acceptable voltage drop of 70 feet (21 meters).
Light power lands on a connector on the side of the control box (see Figure 5-11). When
purchasing optional Will-Burt power cables, these cables are supplied with the mating connector
installed. These cables can handle 20 amp maximum current.
For customer supplied lighting power cables, the customer must supply the connector. The
connector to attach to the power cable is: MIL-DTL-5015 Style, PLUG, 7 PIN, CA3106E24-10S-
F80A206. This connector will mate to the connector installed on the control box.
Plug the source power connector into the control box connector.
5.10.5 Wiring Vehicle Safety Interconnect Circuit
The mast provides an isolated relay contact output to enhance integration into vehicle safety
circuitry. This output indicates whether or not the mast is stowed to indicate it is safe to move the
vehicle. The use of this vehicle safety interconnect is required for vehicle National Fire Protection
Association (NFPA) regulation compliance. The Will-Burt Company does not recommend
installing the mast on a vehicle without connecting to the vehicle safety interconnect circuit to
warn the driver or prevent the driver from moving the vehicle with the mast extended.
This relay output is from a bi-stable (latching) relay whose contacts either open or close (switch
selectable) when the mast is active (not stowed). Its state is not affected by whether or not there
is power to the mast. This contact is capable of carrying up to two (2) amperes and is available
on pins J4-8 and 9 (data cable supplied by the installer). Figure 5-18 shows an example vehicle
safety interconnect circuit. It can be used in conjunction with a customer-supplied relay to drive a
flashing warning light. Other arrangements are possible.

The contact output is set at the factory to be OPEN when the mast is active (not stowed) by
setting the S2-1 Dual In-Line Package (DIP) Switch to the OFF (OPEN) position. To change the
contact output to be CLOSED when the mast is active, set the S2-1 DIP Switch to the ON
(CLOSED) position. Mast power needs to be cycled for this change to take effect.
