7. ELECTRICAL CONNECTIONS
Ensure that the main switch on the power distribution panel is in OFF position (0) and that no one can switch
on the power accidentally before connecting the power cables to the terminals:
L – N to the isolating switch QS1.
THE SYSTEM MUST BE CORRECTLY AND SAFELY EARTHED AS REQUIRED BY THE
REGULATIONS IN FORCE.
CHECK THAT THE DIFFERENTIAL SWITCH THAT PROTECTS THE SYSTEM IS OF
THE CORRECT DIMENSIONS.
