CONNECTION TO POWER MAINS
The air-handling unit is rated for connection to single-phase AC 120V/60 Hz power mains. Connect the unit to power mains using the power
cord with the IEC plug (included in the delivery set).
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 circuit breaker must ensure free access for quick power-off of the unit. The trip
current must be in compliance with the consumption current, refer to Technical data.
Complete the electrical connections through the terminal block in the control unit as shown in the external wiring diagram.
