*) The battery selector switch can be used to select either one of the batteries for normal
starting; parallels the batteries for emergency starting and master disconnect.
If the battery selector switch is placed in position 'BOTH' the batteries are connect-
ed in parallel and isolator function of the diode plitter is by-passed.
Disconnect all batterie cables before installing battery splitter! First
positive wires from battery terminals.
Use cable with sufficient cross-section to connect the battery splitter. Select a wire cross-
section taking into account the maximum current which can be supplied by alternator
and/or battery charger.
Use at least 25 mm
3 ft use at least AWG 2).
Heavy currents through wiring that is too thin, or resistance caused by bad connec-
tions, can generate excessive heat and could cause a fire.
Use good quality interconnection components.
Use matching cable terminals and a suitable crimping tool.
It is very important that the ring of the cable terminal corresponds with the M6 terminal of
the battery splitter. If a cable terminal with an oversize ring is used, the contact surface will
be reduced substantially, as a result the terminals, due to contact resistance, can be over-
heated.
(Generally the battery splitter will carry high currents if a high load is applied to the battery
(bow propeller, anchor windlass, inverter) while at the same time the alternator and/or bat-
tery charger supplies current)
