All connections are made on the terminal blocks
provided for this purpose at the back of the boiler
control panel.
The connecting cables may be brought inside the boi-
ler through the cut-outs provided in the boiler back
panel, which may be used along with purchased cable
channels.
Fasten the cables to the rear plate of the control panel by
means of the cable clamps (cable clamps supplied in a
separate pack) after mounting them on the plate.
IMPORTANT: The maximum current that can be
switched per output is 2 A cos.
ϕ
= 0,7 (= 450 W inrush
current less than 16 A).
Sensor cables must be separated from
cables in 120V circuits.
- In the boiler: use two cable glands on each side of
the boiler for this purpose.
- Outside the boiler: use two cable channels or
cableways with a minimum distance of 10 cm
between them.
