CONNECTION TO POWER MAINS
The air-handling unit is rated for connection to single-phase AC 120V/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 20 AWG.
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 electric lead-ins 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.
