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. To make the connections use the cable termi-
nals 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 outlet of the battery charger.
If the "MASTER" is not connected, the battery charger may supply an output lower voltage than rated and
therefore less power.
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 electri-
cal joints may result in dangerous overheating of the connecting terminals or cables.
