b
Caution.
Risk of damage caused by incorrect
installation.
Mains voltage at the incorrect plug termi-
nals on the ProE system may destroy the
electronics.
> Only connect the mains connection cable
to the terminals marked for the purpose.
> Use a flexible connection cable.
b
Caution.
Risk of damage caused by incorrect
installation.
Connecting wires that have been stripped
too far may cause short circuits and dam-
age the electronics if a strand accidentally
comes loose.
> Only strip the lines a maximum of 3 cm
to prevent short circuits.
> Lay the lines correctly.
> Use strain reliefs.
In IE, reference should be made to the current edition of
the ETCI (Electro-Technical Council for Ireland) rules.
The boiler is supplied for connection to 230 V, ~ 50 Hz sup-
ply fused at 3 A. The connection to the supply network is
made using a 3 A fused double-pole isolator with a contact
opening of at least 3 mm at all poles. A prerequisite here is
that only the boiler and controllers are connected). At the
connection point to the mains, it must be possible to com-
pletely isolate the boiler and its auxiliary controllers electri-
cally. The connection should be easily accessible and adja-
cent to the boiler. Use a three-core flexible cable in accord-
ance with BS 6500, tables 6, 8 or 16
(3 x 0.75 to 3 x 1.5mm
2
).
The rated voltage of each line in the mains must be 230 V;
with mains voltages over 253 V and below 190 V, the unit
may not function properly.
> Open the electronics box (¬section8.2).
> Use a flexible, commercial mains connection cable that is
compliant with standards.
> Guide the mains connection cable through the cable duct
on the left of the base of the unit.
> Use the grommet supplied to seal the cable duct.

8.2 Cable routing of the mains connection cable
> Insert the mains connection cable into the electronics
box.
> Uses the strain reliefs provided.
> Shorten the flexible mains connection cable as neces-
sary.
> Strip the flexible mains connection cable by 2-3 cm, but
not more than 3 cm.
> Insulate the conductor of the flexible mains connection
cable.
> Fit conductor end sleeves on the stripped ends of the
conductors.
> Connect the provided green ProE plug for the mains con-
nection to the flexible mains connection cable using a
screwdriver.
> Insert the ProE plug into the corresponding PCB slot
(L, N and earth) (¬fig.8.2).
> Lay the lines correctly.
> Secure the cable in the electronics box using the strain
reliefs.
> Close the electronics box (¬section8.2).

Ensure that the connection cables are securely
fastened to the plug terminals.
