• Four small cable ties
• Fasteners
Honeywell recommends choosing unswitched power as the source for the power supply. This will allow 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.
