1.10.6 Preparation and connecting to the various utilities
Electricity. Power and control
C A U T I O N
Loose connection terminals produce overheating of cables and terminals. The unit will work incorrectly
and there is a risk of fire.
Power Line
Power must be supplied to the unit through a specific electricity supply line with an exclusive power
control and differential breaker, installed in line with national and local regulations.
N O T E
For further information on this subject, always keep the current regulations for the country where the unit
is being installed at hand.
Make sure that the electricity supply line has enough capacity to power the unit. Its length, the cable
diameter and their protection (cover or jacket) should be appropriate for the unit.
Use a multimeter to check that the supply voltage
remains within the accepted limits.
To install the power cable, loosen the closures -1- by
1/4 turn and remove the electrical board panel.
