CONNECTION TO POWER MAINS
ANY TAMPERING WITH THE INTERNAL CONNECTIONS IS PROHIBITED
AND WILL VOID THE WARRANTY.
DISCONNECT THE UNIT FROM POWER MAINS PRIOR TO ANY OPERATIONS.
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 or 3~400 V/50 Hz power mains.
• The unit must be connected to power mains using insulated electric 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 electric
circuit in case of overload or short-circuit. The circuit breaker installation place must provide quick access for emergency shutdown of
the unit. The trip current of the automatic circuit breaker
QF
must exceed the maximum current consumption of the unit (refer to the
technical data table). The recommended trip current of the circuit breaker is the next current in the standard trip current row following
the maximum current of the connected unit. The automatic circuit breaker is not included in the delivery set.
