Operation Manual

9.4. Power Supply Connection

Plug the pre-assembled cable supplied into the socket at the

rear. The clip on connection is self-locking, however for safety

reasons it is advisable to secure with the pre-set screws. The earth

wire (yellow/green) must be screwed to the GROUND

connection.

The unit was manufactured to operate on a supply voltage of

11V to 15V DC (12V battery). The FMD55 has reverse battery and

over voltage protection. Should an incorrect connection take

place, check the fuse and if necessary, replace.

The power cable is shielded to suppress disturbances. The open

end is ready for connection and is fitted with a terminal strip.

The connection should be as near as possible to the distribution

panel or the battery. It is most important, that the current is

completely free of interference. Should there be any doubt, we

recommend, that you fit a suppression filter.

Fit the cable as follows:

x brown :(-) minus pole 12volt battery

x white :(+) plus pole 12 volt battery

x yellow/green : earth (ground plate)

Before switching on, we recommend you to test the polarity and

the voltage at the terminals on the unit.
