INSTALLATION MTM700/MTM800 Mobile Terminal / Installation Manual 33

Installation Procedure

Begin the DC power cable installation as follows:

1. Determine a routing plan, keeping in mind where the terminal is to be mounted and make

sure that the cable does not rest on sharp edges.

2. Locate an existing hole with grommet in the vehicle fire wall, or use a 9.5 mm (3/8-inch) bit to

drill an access hole in the fire wall. Install a grommet with a 5 mm (3/16-inch) inside diameter

into the hole to protect the power cable.

3. From inside the vehicle, feed the red and black leads (without the lugs attached) through the

access hole and into the engine compartment. (see Figure 1)

4. Connect the black lead of the DC power cable to the nearest vehicle chassis ground point

(using the provided ring lug if necessary). Shorten the black lead to remove any excess cable.

(see Figure 2 Power Cable Assembly).

CAUTION: Improper handling with the power cable may cause shorting to ground.

Ensure that during terminal installation the power cable fuse is removed.

CAUTION: Be very careful not to damage existing wires.

NOTE Locate a good vehicle ground point. The vehicle frame provides the best ground.

Optimum terminal performance can only be achieved with a very low resistance

ground connection. Verify that the connections between the battery negative ter-

minal, vehicle chassis, and engine block have low resistance.
