• The unit is rated for connection to 3~400 V/50 (60) Hz power mains.
• 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 a 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-off. The
automatic circuit breaker nominal current must exceed the ventilator current consumption, refer to the Technical data section. 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 and can be ordered separately.
