Electrical Connections; Electrical Data At Maximum Conditions Allowed (Full Load) - CLIMAVENETA WWR MTD - MTD/s, BWR MTD - MTD/s Installation And User Manual

ELECTRICAL CONNECTIONS

The units leave the factory fully wired. Installation is limited
to connection to the mains electrical supply and connection
of the flow switch and chiller thermal overload switch QF1
(refer to the wiring diagrams).
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.
Respect instructions for connecting phase, neutral and
earth conductors.
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
electricity supply company.

For electrical connections, use double insulation cable
in conformity with legislation in force in the country
where the unit installed..
A thermal overload switch and a lockable mains discon-
nect switch, in compliance with the CEI-EN standards
(contact opening of at least 3mm), with adequate switch-
ing and residual current protection capacity based on the
electrical data table shown below, must be installed as
near as possible to the appliance.
If these devices are not visible from the electrical pan-
el of the unit, they should be lockable.
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 units, ensure the phases
are connected in the correct sequence.
Do not use water pipes to earth the unit.
