Fit the in-line fuse holder in the positive (Red) lead. The fuse protects against short circuits in
the cable run, and so should be located near the battery.
Connect the black cable to the negative battery terminal connector and the red cable to the
positive battery terminal connector.
Note: Both leads of the power cable should be connected directly to the vehicle battery
terminals. Connection to other points may result in increased interference from the vehicle’s
electrical system and excessive voltage drop. If noise is still a problem, an DC noise filter
should be fitted.
In some cases a master isolation switch is fitted to the vehicle (e.g. in the case of emergency
vehicles) and it may be a legal requirement to wire to the switched side of the supply.
If required connect the ignition sense lead to the ignition switched supply on the vehicle.
Plug the power cable into the power supply in-line connector on the mobile radio, and
reconnect the positive lead to the battery.
