CONNECTION TO POWER MAINS

ELECTRICIAN WITH A WORK PERMIT FOR THE ELECTRIC UNITS UP TO 1000 V AFTER
• the unit is rated for connection to 1~230 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.
the trip current of the automatic circuit breaker
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.
the recommended circuit breaker nominal current is 1.0 a.
the conductor section is 0.75 mm².
connect the fan to power mains through the terminal block incorporated inside the terminal box on the fan casing in compliance with
the fan wiring diagram.
airflow direction must be in compliance with the direction of the arrow on the fan casing.
