DISCONNECT THE UNIT FROM POWER
SUPPLY PRIOR TO ANY OPERATIONS WITH THE UNIT.
THE UNIT MUST BE CONNECTED TO POWER MAINS BY A QUALIFIED ELECTRICIAN.
THE RATED ELECTRICAL PARAMETERS OF THE UNIT ARE GIVEN ON THE
MANUFACTURER'S LABEL.
ANY TAMPERING WITH THE INTERNAL CONNECTIONS IS PROHIBITED
AND WILL VOID THE WARRANTY.
The unit is rated for connection to 230 V/50 (60) Hz single-phase alternating current power mains via insulated, durable and thermal-
resistant cords (cables, wires) with respective cross section not less than 2.5 mm
2
. The cable cross-section is given for reference only. The
applicable cable cross section must be selected depending on the wire type, its maximum temperature and insulation, the maximum
current, the wire length and its installation method. Connect the unit to power mains through the external automatic circuit breaker with
a magnetic trip integrated into the fixed wiring system with the rated current not below the rated current consumption.
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 the back side of the lid.
