3.11 CONNECTING POWER SUPPLY
Before connecting power supply, make sure that all connection operations in
the system are completed.
Never connect two devices with power supply unit to one transformer.
Before adding transformer to a circuit from which it will be powered, make sure
the circuit is de-energized.
Because the transformer has no mains switch, it is important that you let the
owner / user of the device know how it should be disconnected from the mains
(e.g. by indicating the fuse which protects the control panel supply circuit).
It is not allowed to connect a fully discharged battery (with voltage across
unloaded terminals less than 11 V) to the alarm panel. If the battery is fully
discharged or it has never been in use, precharge it by means of a suitable
charger.
