• The unit is electrical safety class III.
• The nature of the installation where it is connected must not exceed OVC II.
• The unit must be powered with class DVC A power supply with a PELV protection output
voltage.
7.4.2 Protection against over-voltage and reverse voltage.
Protection against over-voltage and reverse voltage. The central unit has a F2A fuse that
may be accessed from the outside to protect against over-voltage (greater than 36 V DC or
25 V AC). The central unit is also protected against reverse connection of the power supply.
7.4.3 Voltage supply at 24 V DC.
Universal DC power supply. Use a regulated 24 V DC power supply (between -15% and
+20%) and 2 A (including voltage ripple and noise). See
