Electrical connections: Preliminary Information Security
The electrical panel is located inside the unit at the top of the technical compartment where there are
also the components of the cooling circuit. To access the electrical panel, remove the top panel of the
unit and the panel of the compressor compartment.
The connection must be made by a qualified electrician using wiring diagram provided with
the machine, or according to local regulations and international standards.
Make sure that the
power supply line
of the unit is
sectioned
upstream of the unit itself
.
Make sure that
the disconnecting device
is
padlocked
or
that
the appropriate
“
not to
operate” warning sign
is applied to
the
operating handle
.
Verify that the power supply corresponds to the nominal data of the machine (voltage,
phases, frequency) reported on the wiring diagram and the rating plate attached to the
unit.
The power cables must be protected upstream against the effects of short-circuit and
overload by an appropriate device complies with regulations and laws.
The section of the cables must be commensurate with the calibration of the “upstream
protection” system and must consider all the factors that may influence it (temperature,
type of insulation, length, etc.).
The power supply must comply with the limits shown: otherwise, any guarantee will
terminate immediately.
Make all
ground connections
required by the regulations
and
legislation.
Before carrying out any operation, ensure that supply voltage are disconnected.
Electrical data
The electrical data below refer to the standard unit without accessories.
In all other cases, refer to the data reported in the electrical circuit diagrams.
The supply voltage must be within ± 10% of the nominal value and the imbalance between
phases must be less than 1% according to EN 60204. If those tolerances should not be
respected, please contact our technical department.
The electrical data can change without notice. It is therefore necessary to refer always to the wiring
diagram supplied with the unit.
