7.3. Connecting the boiler to the mains power supply
The boiler must be connected to a 220V / 50Hz mains using a cable and a plug. The
boiler must be placed in a position which allows for unobstructed access to the
power supply plug. Dismount the inspection cover on the back side of housing.
Using a screw driver, connect the power supply and the external components (pump
for the heating circuit and domestic hot water pump). Make sure you have
connected the external components properly according to the enclosed wiring
diagram.Create solid connection with the electrical mains which complies with the
local regulations.
Warning! Be careful when connecting the circulation water pumps: the
controller is only capable of sending signals (voltage) for controlling the
pumps and is incapable of powering them up with electric current (see
10.16)!
Caution! ELECTRIC SHOCK HAZARD! Before opening the switchboard:
switch off the voltage and secure the switchboard against accidental
restart. Observe installation instructions.
Make sure that the power supply system is properly grounded.
All connection works must only be carried out by qualified electricians.
Improper cable connections may damage the regulator! The device may be
damaged if struck by a lightning. Make sure it is unplugged during the
storms. It is mandatory to assure a backup power generator of
corresponding rated power! (see 12.2)
