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 that simultaneously
isolates all non-earthed conduc-
tors 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 connection of
accessories to the power supply
must not be carried out at the
control unit. The power supply
connection for accessories can
be made immediately at the
control unit, if the boiler is
installed outside wet areas. This
connection is directly controlled
with the system ON/OFF switch
(max. 3 A).
