DISCONNECT THE UNIT FROM POWER MAINS PRIOR TO ANY OPERATIONS. THE FAN MUST
BE CONNECTED TO POWER MAINS BY A QUALIFIED ELECTRICIAN. THE RATED ELECTRICAL
PARAMETERS OF THE UNIT ARE GIVEN ON THE MANUFACTURER'S LABEL.
ANY INTERNAL CONNECTION MODIFICATIONS ARE NOT ALLOWED AND RESULT IN
WARRANTY LOSS.
The fan is rated for connection to single-phase or three-phase AC power mains with a voltage of 230 V or 400 V according to the wiring diagrams below.
The terminal designation is placed inside of the terminal box.
The terminal clamp marking corresponds to the marking on the wiring diagram.
Connect the fan to power mains by means of insulated, durable and thermal-resistant cords (cables, wires) with appropriate cross section.
The cables are routed into the terminal box through a sealed lead-in for electrical hazard class compliance.
The fan shall be connected to power supply through the external circuit breaker with a thermal-magnetic trip. The rated current of the circuit breaker
must be not below the rated current consumption.
