CONNECTION TO POWER MAINS
POWER OFF THE POWER SUPPLY PRIOR TO ANY OPERATIONS WITH THE UNIT.
THE UNIT MUST BE CONNECTED TO POWER SUPPLY BY A QUALIFIED ELECTRICIAN.
THE RATED ELECTRICAL PARAMETERS OF THE UNIT ARE GIVEN ON THE
MANUFACTURER’S LABEL.
• The unit is rated for connection to 1~230 V/50 Hz according to the wiring diagram.
• The connection must be made using insulated conductors (cables, wires).
• The actual wire cross section selection must be based on the maximum load current, maximum conductor temperature depending
on the wire type, insulation, length and installation method.
• The external power input must be equipped with an automatic circuit breaker QF built into the stationary wiring to open the circuit
in the event of overload or short-circuit.
• The position of the automatic circuit breaker must ensure free access for quick power-off of the unit.
• The trip current of the automatic circuit breaker must exceed the maximum current consumption of the unit (refer to the “Technical
data” section or to the unit label).
• It is recommended to select the nominal current of the circuit breaker from the standard series, following the maximum current of
the connected unit.
• The circuit breaker is not included in the delivery set and can be ordered separately.
