Important Note: The charger unit is fused internally with 2 A automotive re-settable thermal fuse, but if an external fuse is to be installed then connect a 2 A fuse holder and fuse inline with the Red wire close to the power source. Route the cable from the holder into the vehicle dashboard and secure the charger unit in place with the adhesive tape provided. Ensure the charger unit is securely mounted behind the dashboard in a well ventilated area that does not get hot! Connect as follows: 1. Connect the White wire to a Negative Ground connection of the vehicle or the vehicle chassis. 2. Connect the Red wire to a 12/24 Volt power supply in the vehicle that is controlled by the ignition switch of the vehicle. Installation of the holder:
Please read all of the instructions and look at the pictures before attaching the holder. 1. Loosen the screw in the center of the holder so you can remove the tilt swivel attaching plate on the back. 2. Place the attaching plate onto the desired position. Screw the attaching plate into place with the enclosed screws. 3. Place the holder over the attaching plate so the screw fits in the hole in the tilt swivel. Tighten the screw until the holder is firmly in place, but still can be adjusted. 4. The holder is in place in upright and horizontal position.
