Danger
Incorrect core terminations
can cause severe injuries
and damage to the equip-
ment.
Take care not to inter-
change wires "L1" and "N".
&Install an isolator in the power
supply line which simulta-
neously separates all non-
earthed conductors from the
mains with at least 3 mm contact
separation.
&Max. fuse rating 16 A.
lH &Power supply accessories (230
V ~ 50 Hz). Where the boiler is
installed in a wet area, the con-
nection of accessories to the
power supply must not be car-
ried out at the control unit. The
power supply connection for
accessories can be made imme-
diately at the control unit, if the
boiler is installed outside wet
areas. This connection is
directly controlled with the sys-
tem ON/OFF switch (max. 3 A).
