Connecting the a500 VMT Device to a Vehicle's Power Source

You need the following equipment:

• Two fuse holders from Cooper Bussman. Honeywell recommends using a Cooper Bussmann HFA series in line waterproof fuse.
• Two fuses. Honeywell recommends a 4A 250V SLO BLO fuse.
• Three spade connectors
• Four small cable ties
• Fasteners

Honeywell recommends choosing unswitched power as the source for the power supply. This allows Talkman devices to be powered for software updates as well as prevent Talkman devices from accidentally being unpowered if the vehicle is quickly switched off unintentionally.

1. Remove all power sources from the vehicle.
2. Remove any excess length from the input cable that comes from the power supply.
3. Connect the fuses to the cable near to the battery end of the cable. Remove approximately 4 inches of the outer insulation from the cable.
4. Expose approximately 10mm of copper on the positive and negative wires.
5. Insert the exposed copper into the fuseholders and crimp into the positive and negative wires using an approved tool.
6. Connect the green wire to the vehicle's ground.
7. Connect the fused white wire to the vehicle’s positive power source using an appropriate connector. This may need to be crimped onto the wire.
8. Connect the fused black wire to the vehicle’s negative power source using an appropriate connector. This may need to be crimped onto the wire.
9. Attach the power supply as shown in the following diagram.

   

10. Secure the wires with cable ties.
