The air-handling unit is rated for connection to single-phase AC 230 V / 50/60 Hz power mains. The connection must be made using
durable, insulated and heat-resistant cables with a minimum cross-section of 1.5 mm
2
(up to 50 m long). The cable cross-section is given for
reference only. The actual conductor cross-section selection must be based on its type, the maximum permissible heating, insulation, length
and installation method.
Use copper cables only.
Connect the unit to power mains on the terminal block which is located in the control unit in compliance with the wiring diagram and the
terminal marking.
Connect the unit to power mains through the external automatic circuit breaker with a magnetic trip integrated into the fixed wiring
system. The trip current of the automatic circuit breaker must correspond to the current consumption (see the table on page 6).
