Fig. 18. Routing the Electrical Cables
î
When the appliance is con-
nected to the electrical net-
work, it must be earthed.
î
Make sure that a fuse or circuit breaker
of the recommended rating is installed
outside the appliance, to allow electri-
cal isolation.
î
Do not touch the appliance with any
wet body parts when it is supplied with
electrical power.
î
Before performing any operation on
the electrical circuit, isolate the electri-
cal supply of the appliance through the
external power-cutting device (fuse,
circuit-breaker, etc.)
î
When routing the cables through
sharp-edged holes in the panels, make
sure to install glands or grommets, and
to secure the cables in order to prevent
any damage.
î
Make sure to make the con-
nections to the correct termi-
nals, as indicated on the wir-
ing diagram. If high voltage
cables are installed on a
low-voltage terminal, the elec-
tronic board will be damaged.
î
When connecting wires to the termi-
nals, check that the connection is se-
cure and that all the wire strands are
tightly held
Electrical connections must be carried
out by a qualifi ed professional in accord-
ance with current standards and regula-
tions in force.
Cables
î
Any damaged power supply ca-
ble must be replaced using ca-
bles as described below and in-
stalled by a qualified professional.
î
The cross-section of the wires should
be >2.5 mm
2
, equipped with sleeves at L,
N and grounding ends.
High voltage wiring is connected to a terminal strip
located at the back of the appliance.
The main board and the low-voltage terminal strip
are ocated at the front of the appliance.
