CONNECTION TO POWER MAINS

THE UNIT MUST BE CONNECTED TO POWER SUPPLY BY A QUALIFIED ELECTRICIAN.
The air-handling unit is rated for connection to single-phase AC 230 V/50 (60) Hz power mains. The unit must be connected to power
mains using durable, insulated and heat-resistant conductors (cables and wires) with minimum cross section not less than 1 mm
The external power input must be equipped with an 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 automatic circuit breaker must ensure free access for quick power-off of
the unit. The circuit breaker trip current must correspond to the unit current consumption, refer to the Technical data section.
Connect the cables to the control unit using the cable glands on the side of the unit.
Make the electric connections through the terminal block, located in the control unit, in compliance with the External wiring diagram.
