The MRU, the LBPA, and the control head require separately-fused main DC power. This is the red wire
of each DC power cable. The switch power source to the control head is also separately fused. This is the
white wire of the control head’s DC power cable. In-line type fuses and fuse holders are utilized.
9.2 POWER INSTALLATION PROCEDURE
9.2.1 Radios DC Power Cables and Main Fuse Holders Installation
Each radio’s DC power cable has a connector which mates to the radio’s power cable, a 20-foot red wire
for the main power connection, a 20-foot white wire which is not used/not connected in this application,
and a 4-foot black wire for the ground connection.
Cable CA-012365-001 is used with the XG-100M and has a 3-pin connector. It is supplied with HFB-type
waterproof fuse holders, two AGC-type fuses, and non-insulated ring terminals.
Cable 14002-0167-01 is used with the XG-100LPA and has a 5-pin connector. It is supplied with an
HEB-type water-resistant fuse holder, heat shrink tubing, a BAF-type 30-amp fuse, and non-insulated ring
terminals.
The following installation procedures are recommended:
9.2.1.1 Black Wire Connections (Ground Wires)
1. Connect the radio’s DC Power Cable to the MRU by mating its connector to the radio’s 3-pin DC
power cable connector. 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.
Do not confuse the radio’s DC Power Cable which has a 6 or 10-AWG red wire with the
control head’s DC Power Cable which has a 12-AWG red wire. A radio requires more DC
operating current than the control head, and therefore, larger-gauge power wires (of 6 or
10-AWG). For a radio, the DC Power Cable’s part number is CA-012365-001 (has
10-AWG red wire). For the LBPA, the DC Power Cable’s part number is 14002-0167-
01 (has 6-AWG red wire). Control head DC Power Cable installation procedures are
provided in Section 10 of this manual.
2. Connect the other DC Power Cable to the LBPA using the same connection method.
3. Prepare to connect both cables’ black wires to vehicle ground by locating an area of vehicle metal
within approximately three (3) feet of the two units. This surface must have a solid and stable
connection to vehicle ground (i.e., battery ground).
