4 Electrical installation
4.1 Electrical system engine (12 volt)
IMPORTANT
The electrical system is carried out in 12 Volt with negative ground.
The electrical wiring has already been fitted to generator set and the built-in control panel.
The battery cables (as supplied) have a standard length of 2.5 metre (8’ 4”); if longer cables are needed a larger cross-sec-
tion may be required. The permissible voltage drop on both the positive and negative lead between starter motor and
battery must not exceed 8 %.
The battery cables are already connected inside the generator set housing.
The positive battery cable (RED) to the positive (+) terminal of the starter motor relay and the negative battery cable
(BLACK) to the engine motor block.
Connect the battery cables to the battery terminals. Install a battery main switch in the positive cable.
Never use the hull, in case of a steel vessel, as earth return!
Connection of the negative terminal(s) of the battery(ies) to the steel ship’s hull, for earthing purposes, is permissible at
one point only.
NOTE
The wiring system for the engine and the domestic supply must be kept completely
separate and must be individually connected to the batteries.
IMPORTANT
Disconnect the battery cables if electrical welding has to be done. Otherwise, the weld-
ing can damage the diodes of the alternator.
4.1.1 Remote control panel
If required a remote control panel can be connected to the gen-
erator set.
Remote control panel complete with 6 meter (19 ft 8in) connec-
tion cable, Vetus art.code:
