• the unit is rated for connection to 1~230 V/50 or 3~400 V/50 (60) 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.
