7.5 Electrical connections
7.5.1 Electrical recommendations
Only qualified professionals may carry out electrical connections, always
with the power off.
Separate the very low voltage cables from the 230V circuit cables.
The electrical power supply is done by means of a mains connection cable
(~230 V, 50 Hz) in accordance with prevailing national regulations for
electrical installations.
Respect the polarities when making the electrical connections to the
mains:
Brown wire (L) : Live
Blue wire (N) : Neutral
Green/yellow wire : Earth
1. If the power supply cable is damaged, you must have it replaced by a
qualified installer.
2. Do not connect the power supply directly to the peak/off-peak rate
contact.
