Connection To Power Mains - Vents VKM EC Series User Manual

CONNECTION TO POWER MAINS

THE UNIT MUST BE CONNECTED TO POWER SUPPLY BY A QUALIFIED ELECTRICIAN.
The unit is rated for connection to single-phase ac 120 V/ 60 Hz power mains. For electric installations use insulated durable heat-resistant
conductors (cables, wires) with the minimum wire cross section AWG19. The conductor cross section value must be selected on the wire
type, maximum permissible heating temperature, insulation, length and installation method.
Connect the fan to power mains via an external automatic circuit breaker installed at the power input and integrated in the house cabling
to open the circuit in case of short circuit or overload.
The circuit breaker location must provide quick access for emergency shutdown of the fan.
Connection of the fan to power supply is performed via the terminal block located in the terminal box attached to the fan casing in
compliance with the wiring diagram and designation of terminals.
For smooth air flow control it is recommended to use the speed controller R-1/010.
The speed controller is not included in the delivery set and is available as a specially ordered accessory.
