CONNECTION TO POWER MAINS
THE UNIT MUST BE CONNECTED TO POWER SUPPLY BY A QUALIFIED ELECTRICIAN.
•
The unit is rated for connection to 1~230 V/50 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 an automatic circuit breaker QF built into the stationary wiring to open the circuit in
the event of overload or short-circuit.
•
The position of the external automatic circuit breaker must ensure free access for quick power-off of the unit.
•
The automatic circuit breaker nominal current must exceed the ventilator current consumption.
•
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.
•
The unit must be connected to power mains through a double pole circuit breaker of suitable rating integrated into the fixed wiring
system with opening of contacts at all poles. The gap between the circuit breaker contacts at all poles must be not less than 3 mm.
Follow the wiring diagram to connect the fan using the power cable.
