Vetus BS1502C Installation Instructions Manual page 10

If the battery selector switch is placed in position 'BOTH' the batteries are connected
in parallel and isolator function of the diode splitter is by-passed.

ISCONNECT ALL BATTERIE CABLES BEFORE INSTALLING BATTERY SPLITTER
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.
Max. 120 A ⇒ 25 mm
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 M8
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 con-
tact resistance, can be overheated.
(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 alter-
nator and/or battery charger supplies current)
2.3 Function of the terminals
B+ ALTERNATOR
- Connect to the B+ terminal of the alternator.
- Where a battery charger is installed then also connect the battery charger plus
(+) to this terminal.
Instead of 'B+' one of the following markings may be shown: B+51, 51, B+30, B, BAT
or 30.
Normally the B+ terminal of the alternator is connected to that plus (+) terminal of
the starter relay where also the plus cable of the starter battery is connected.
