Power Cable Routing--All Installations
1. Once the mounting location of the IMR is known, select a location in the vehicle for the IMR
connector end of the cable so that it reaches the Itron Mobile Radio power jack without put-
ting stress on the cable or radio.
2.
Route the vehicle accessory adapter end of the cable to the desired voltage and ground-
ing sites in the vehicle, typically either an accessory jack for a removable installation or
the fuse block for a permanent installation. Leave enough slack in the cable to work with
it and so it is not stressed during use.
Caution: Do not route the cable where it can become abraded or damaged, such as under
the carpet in high traffic areas, over sharp edges, near hot engine components, near brake or
clutch linkages, or where it can be exposed to oil or other corrosive liquids.
Power Cable Installation--Removable
To temporarily install the DC power cable using the vehicle accessory adapter, route the
adapter end of the cable to a 12V DC accessory jack and plug the adapter in securely. To
remove the adapter, grip the adapter body and pull; do not pull on the cable.
Note: Some accessory jacks are unswitched and have power always
on, and some are switched by the vehicle ignition key. Determine which
accessory jacks you have and which you intend to use before routing the
cable.
Power Cable Installation--Permanent
1. To permanently hard wire the DC power cable, first remove the vehicle accessory adapter
from the DC power cable by cutting the cable where it connects to the adapter. Dispose of
the adapter properly.
2. Route the unterminated end of the cable to the fuse block or other 12V DC source. If neces-
sary, trim the cable wires to a suitable length and strip the insulation from the wires according
to the requirements of the installation.
3. Connect the plain black wire (without white writing) to a spare fuse location in the vehicle
fuse block that has a rating of five amps. If no spare fuse location is available, a five amp
inline fuse must be spliced into the positive side of the cable. Then the wire can be connected
to either a switched or unswitched 12V DC power source, depending on the user require-
ments.
Caution: When hard wiring the DC power cable to the vehicle a five ampere fused con-
nection is required.
4. Connect the black wire with white writing directly to the vehicle's chassis ground.
