2.3.- Components.
2.3.1.- Batteries.
The supervised battery input/output allows the connection of batteries to the control panel. The
batteries are charged through this connection as well as the monitoring of its status. The battery charge is
compensated depending on the temperature of the batteries. This input/output is protected by a fuse and also
against inversion of polarity. In addition to this fuse there is the battery charger fuse.
The capacity of the batteries that are incorporated into the control panel will depend on the number
of loops and additional loads (e.g. relays modules), 7Ah being the minimum recommended. Batteries with a
capacity of 15Ah or 24Ah will have to be housed in a box external to the control panel,
ref C-55.
Connection of the two 12V batteries in series is exactly as indicated in figure 18.
