VUT 2000/3000 PBE EC
DISCONNECT THE UNIT FROM POWER MAINS PRIOR TO ANY OPERATIONS.
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 three-phase 3~400 V/50 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 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.
