4.6 Connect the power cable
A power cable is NOT supplied with the radar processor. A fuse / circuit breaker must be used
on the power cable supplying the radar processor.
Check the system specifications section for the recommended DC input voltage.
The power cable and fuse/circuit breaker requirements are shown in the table.

2 kW 12 V DC ONLY 5 A 10 m (33 ft) 14 AWG
4 kW 12-24 V DC 10 A 8 m (26 ft) 14 AWG
Typically the fuse/circuit breaker would be located in a fuse/circuit breaker box with the
fuses/circuit breakers for other devices.
The radar processor must have its own exclusive fuse/circuit breaker. The fuse/circuit breaker
should be labeled appropriately.
To connect the power cable to the radar processor, you must:
•
Strip away approximately 0.4" (10 mm) of the shielding at the end of the power cable,
and then identify the positive wire and the negative wire
• Unscrew the small holding screw from the positive power cable input connector (identified
by the + sign) on the radar processor
•
Insert the bare end of the positive wire into the positive power cable input connector to
make a connection
•
Tighten the small holding screw to hold the positive wire in place. Gently pull on the
positive wire to ensure that it is secured
• Repeat this process to connect the negative wire to the negative power cable input
connector (identified by the – sign)
Note 2 kW system is for 12 V DC only.
