CONNECTION TO POWER MAINS
POWER OFF THE POWER SUPPLY PRIOR TO ANY OPERATIONS WITH THE UNIT.
THE UNIT MUST BE CONNECTED TO POWER SUPPLY BY A QUALIFIED ELECTRICIAN.
THE RATED ELECTRICAL PARAMETERS OF THE UNIT ARE GIVEN ON THE
MANUFACTURER’S LABEL.
• The unit is rated for connection to 1~230 V/50-60 Hz power mains.
• The unit must be connected to power mains using insulated electric conductors (cables, wires). The actual wire cross section
selection must be based on the maximum load current, maximum conductor temperature depending on the wire type, insulation,
length and installation method.
• The external power input must be equipped with an automatic circuit breaker built into the stationary wiring to open the electric
circuit in case of overload or short-circuit. The circuit breaker installation place must provide quick access for emergency shutdown
of the unit. The trip current of the automatic circuit breaker
QF
must exceed the maximum current consumption of the unit (refer
to the technical data table). The recommended trip current of the circuit breaker is the next current in the standard trip current row
following the maximum current of the connected unit. The automatic circuit breaker is not included in the delivery set.
Connection of unit contacts is carried out in the control unit
To access the control unit, open the unit door, remove the
protective panel, undo the screws securing the side wall, and
remove it.
Connection of the automatic fire fighting system contact (PK)
Remove the jumpers between the terminals 5 and 6. In case of fire, the normally closed dry contact breaks the control circuit from the
central fire-fighting board and cuts off power supply to the unit.
Connection of the contact for activating the Boost mode
The unit provides for the connection (parallel to the humidity sensor installed at the factory) of a normally open contact for activating the
Boost mode. When the contact closes, the unit switches to maximum speed.
