To prevent damaging the radio, always connect power cables before connecting the Ethernet
cables.
If only removing the transceiver, always disconnect the Ethernet cable first and then the power
cable. When reinstalling the transceiver, always connect the power cable before connecting the
Ethernet cable.
Do not confuse the radio’s DC Power Cable which has a 10-AWG red wire with the Control
Head’s DC Power Cable which has a 12-AWG red wire. The radio requires much more DC
operating current than the Control Head. Therefore, it requires the larger wire size of 10-AWG.
The part number of the radio’s DC Power Cable is CA-012365-001 and it has two wires
which are 20-feet long.
In a typical vehicle installation, as a time saving measure, most of the length of the Ethernet cable between
the remote-mount radio and the Control Head can be routed together with the red wire of the radio’s DC
Power Cable. Also, any necessary option/accessory cables from the back of the radio can also be routed
with this wire and cable.
The following wire and cable installation procedures are recommended:
9.2.1 Radio Power Ground (Black Wire) Connection
Use the following procedure to provide a suitable ground connection for the radio:
1. Obtain the radio’s DC Power Cable, part number CA-012365-001.
2. Temporarily connect this cable to the radio by mating the cable’s 3-pin connector to the radio’s 3-pin
power connector. Locking the two connectors is not necessary at this time.
3. Prepare to connect the cable’s black wire to vehicle ground by locating an area of vehicle metal within
approximately two (2) feet of the radio. This surface must have a solid and stable connection to vehicle
ground. If not, add grounding strap(s) as necessary.
4. Verify the black wire has sufficient length to reach the ground point. If not, it can be extended by
splicing a 10-AWG wire to it. In this case, use approved wiring splicing methods and materials.
5. Strip the area of any paint or dirt to expose a bare metal surface, approximately ¾-inch square.
6. Drill a hole in the approximate center of the bare metal surface and deburr it. A ⅜-inch non-insulated
ring terminal is supplied with the cable to make this ground connection. Therefore, hole diameter should
be appropriate for the utilized grounding screw/bolt size and type used to connect the ring terminal to
the bare metal surface. This hardware is not supplied.
7. Prepare the ground (black) wire:
a. Cut the black wire to the required length plus some additional length for a service loop.
b. Strip insulation back approximately ¼-inch.
c. Crimp a ⅜-inch non-insulated ring terminal (supplied with the cable) to the end of the black wire.
8. Fully connect the cable to the radio by mating its 3-pin connector to the radio’s 3-pin power connector
as follows:
Visually align the key and firmly push and turn the outer locking ring clockwise until it stops. A click
will be sensed to confirm proper mating.
