4.4 MAINS AND BATTERY CONNECTIONS
Figure 28 – Connection to mains
The control panel power supply must be connected to 220÷240 V~ mains with a 2-core mains cable with
double insulation and a magnetothermic/differential switch. It is suggested to connect the control panel
power supply before the residual current circuit breaker, in order to be able to disconnect mains and at the
same time keep active the alarm system power supply.
On the power supply unit, the screw terminal pins for 220÷240 V~ cable are labelled as PH (phase) and N
(neutral); in the near fin used for power supply fixing there is a slot for the cable tie passing, in order to
block cables.
Figure 29 – Fixing of 220÷240 V~ mains cable
The power supply output (OUTPUT) is connected by default to the terminal pins POWER of the
motherboard. The backup battery must be connected to cables with faston connectors already installed in
factory: the red cable must be connected to the battery positive pole, the black cable to the negative pole.
