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.
ANY TAMPERING WITH THE INTERNAL CONNECTIONS IS PROHIBITED
AND WILL VOID THE WARRANTY.
DO NOT LAY THE CABLE IN CLOSE PROXIMITY TO THE CONTROL PANEL CABLE!
WHILE ROUTING THE CONTROL PANEL CABLE DO NOT COIL THE EXTRA LENGTH.
After mounting the unit, make internal connections according to the label on the casing.
To access the terminal block, remove the fixing screws and remove the cover.
The unit with a drain pump is designed to be connected to 1~230 V/50 Hz or 3~400 V/50 Hz power mains,
without a drain pump — 1~230 V/50(60) Hz or 3~400 V/50(60) Hz.
The drain pump is not included in the delivery set and must be ordered separately.
The unit is rated for connection to 3~400 V/50 (60) Hz power mains according to the wiring diagram.
The connection must be made using durable, insulated and heat-resistant 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 built into the stationary
wiring to open the circuit in the event of overload or short-circuit. The position of the external circuit breaker must ensure free access for
quick unit power-o
ff
.
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 rated 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.
To access the terminal block, remove the fixing screws and remove the cover.
Route the cables to the terminal block unit through the sealed cable glands in the unit.
Complete the electrical connections as shown in the external connections diagram.
