CONNECTION TO POWER MAINS

The unit is rated for connection to single-phase ac 230 V/ 50-60 Hz power mains. For electric installations use insulated durable heat-

resistant conductors (cables, wires) with the minimum wire cross section 2.5 mm

2

.The above conductor cross section value is tentative 

and in practice must be based on the wire type, maximum permissible heating temperature, insulation, length and installation method.

Connect the unit to power mains through the external automatic circuit breaker with magnetic trip integrated into the fixed wiring 

system with the rated current not below  the rated current consumption (refer to page 6). 

The terminal block with the prewired control unit is located inside the control unit compartment. To connect the power and the 

ground cable route the cables through the airtight electric lead-in in the unit casing and connect these to the terminal block. The wiring 

diagram for connection of the air handling unit to power supply is on back side of the lid.
