n Installing the Junction Box
The Car Kit is designed to work with the 12/ 24-volt power
supply of the vehicle. Refer to the following to install the
junction box in a vehicle.
1. Locate a suitable place inside the car to mount the
junction box. Select a dry place that avoids excessive
heat and mechanical vibration. Ideally, the junction box
should be hidden from view, but still easily accessible.
Note:
Make sure that the cables are long enough to support
the location of the junction box. If the cables are not long
enough, do not lengthen the cables. Instead, relocate the
junction box.
2. Use two screws (not included) to fasten the junction box
in place.
