INSTALLATION
1. Low voltage disconnect units feature a fully sealed (IP65) shock proof aluminium housing, protecting
the unit against water and dust ingress. The LVD end plates include a mounting flange for easy mounting,
if permanently fixed the LVD should be mounted to a suitable horizontal or vertical panel. Mount in a
convenient location. Mount as far away as possible from the exhaust manifold, turbo or any other high
temperature components. Do not mount on the engine.
2. Disconnect the negative battery cable (Ground) from the starting battery.
Note: To prevent the loss of the vehicle’s electronic memory, preset radio and security codes it is
recommended that an ‘Electrical System Memory Protector’ (P/No. IPS700) be used.
3. Connect the LVD ’INPUT’ (+) wire to the battery.
Note: For safety reasons it is recommended to install a fuse close to the battery.
4. Connect the LVD ‘OUTPUT’ (+) wire to the auxiliary load.
5. Connect the LVD ‘GROUND’ (-) wire (small black wire) to a suitable chassis bolt or screw ensuring a good
electrical connection is made.
6. Reconnect the main/starting battery’s negative cable (Earth).
7. The ‘REMOTE’ wire must be connected to a positive 12V power source for the LVD to operate.
a) Connect ‘REMOTE’ wire to the vehicle’s ignition or accessories switch. The LVD will operate only when
the ignition or accessories switch is turned on. Install a fuse to the remote wire as close as possible to
the ignition switch.
Note: Fuses used when wiring the LVD unit should be rated to the cable being used for the installation.
b) For continuous operation connect the ‘REMOTE’ wire to the LVD positive ‘INPUT’ wire.
Note: Fuses used when wiring the LVD unit should be rated to the cable being used for the installation.
