SINGLE BATTERY CHARGER
The positive terminal of the battery or of the group of batteries must be connected to one of the positive terminals of
the battery charger. The negative terminal of the battery or of the group of batteries must be connected to the negative
terminal of the battery charger (fig. 1). To make the connections use the cable terminals supplied with the equipment.
If the installation has only one or two groups of batteries, always connect the output marked "MASTER". This is
the main output of the battery charger. It is advisable to connect the group of batteries which are used more often
(typically the service group) to the MASTER output terminal.
The positive output terminals that are not used must be kept free (do not bridge the terminals).
BATTERY CHARGER IN PARALLEL
The "MASTER" positive terminal is to be connected to junction "JM"; junction "JM" is to be connected to the positive
terminal of the battery or group of batteries (fig. 2A).
The "SLAVE 1" positive terminal of the battery charger is to be connected to junction "JS1"; junction "JS1" is to be con-
nected to the positive terminal of the battery or group of batteries (fig. 2A).
The "SLAVE 2" positive terminal of the battery charger is to be connected to junction "JS2"; junction "JS2" is to be con-
nected to the positive terminal of the battery or group of batteries (fig. 2A).
The negative terminal of the battery charger is to be connected to junction "JCN"; junction "JCN" is to be connected to
the negative terminal of the battery or group of batteries (fig. 2A).
The lengths of cables that run from the terminals of the battery chargers to the junctions must be the same and never
exceed 2 m (fig. 2B).
If the installation has only one or two groups of batteries, always connect the output marked "MASTER". This is
the main output of the battery charger. It is advisable to connect the group of batteries which are used more often
(typically the service group) to the MASTER output terminal.
The positive output terminals that are not used must be kept free (do not bridge the terminals).
WARNING: the use of inadequate size cables and the incorrect connection of terminals or electrical joints may
result in dangerous overheating of the connecting terminals or cables.
