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. If the MASTER output 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 electrical joints
may result in dangerous overheating of the connecting terminals or cables.
