Connect Vehicle 12Vdc Connection - Honeywell MX7 User Manual

Connect Vehicle 12VDC Connection

1. The power cable must be UNPLUGGED from the MX7 vehicle cradle.
2. While observing the fuse requirements specified above, connect the power cable as close as possible to the actual
battery terminals of the vehicle. When available, always connect to unswitched terminals in the vehicle fuse panel, after
providing proper fusing.
ATTENTION: For uninterrupted power, electrical supply connections should not be made at any
point after the ignition switch of the vehicle.
3. Route the power cable the shortest way possible. The cable is rated for a maximum temperature of 105°C (221°F).
When routing this cable it should be protected from physical damage and from surfaces that might exceed this
temperature. Do not expose the cable to chemicals or oil that may cause the wiring insulation to deteriorate.
Note: If the vehicle is equipped with a panel containing Silicon Controller Rectifiers (SCR's), avoid routing the
power cable in close proximity to these devices.
Always route the cable so that it does not interfere with safe operation and maintenance of the vehicle.
Use proper electrical and mechanical fastening means for terminating the cable. Properly sized "crimp" type
electrical terminals are an accepted method of termination. Select electrical connectors sized for use with
18AWG (1mm2) conductors.

4. Provide mechanical support for the cable by securing it to the vehicle structure at approximately one foot intervals,
taking care not to over tighten and pinch conductors or penetrate outer cable jacket.
5. Refer to the following sections to complete the power connection to the MX7 vehicle cradle.
