ELECTRICAL CONNECTIONS
I A
The heat pumps must be installed downstream of a main
switch (QF1, see wiring diagram), as required by the stan-
dards in force in the country where the unit is installed. Con-
nection to the mains power supply and the connection of the
flow switch to the corresponding terminals must be per-
formed by authorised personnel in compliance with the stan-
dards in force.
For all electrical work, refer to the electrical wiring diagrams
in this manual.
It is also recommended to check that:
- The characteristics of the mains electricity supply are ade-
quate for the power ratings indicated in the electrical spec-
ifications below, also bearing in mind the possible use of
other equipment at the same time.
Power to the unit
must be turned on only after installa-
tion work (plumbing and electrical) has been completed.
All electrical connections
must be carried out by quali-
fied personnel in accordance with legislation in force in
the country concerned
Respect instructions
for connecting phase, neutral and
earth conductors..
The power line should be fitted upstream with a suitable
device to protect against short-circuits and leakage to
earth, isolating the installation from other equipment.
Voltage
must be within a tolerance of ±10% of the rated
power supply voltage for the unit (for three phase units,
the unbalance between the phases must not exceed 3%).
If these parameters are not respected, contact the elec-
tricity supply company.
For electrical connections
, use double insulation cable
in conformity with legislation in force in the country con-
cerned..
A thermal overload switch and a lockable mains dis-
connect switch, in compliance with the CEI-EN stan-
dards (contact opening of at least 3mm), with ade-
quate switching and residual current protection
capacity based on the electrical data table shown
below, must be installed as near as possible to the
appliance.
An efficient earth connection
is obligatory
.
The manufacturer cannot be held liable for any damage
caused by the failure to correctly earth the unit.
In the case of three phase unit
s, ensure the phases
are connected correctly.
Do not use
water pipes to earth the unit.
