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.
CONNECTION TO POWER MAINS
The ventilator is rated for connection to single-phase AC 100-240 V 50/60 Hz power mains.
For electric installations use insulated, flexible conductors (cables, wires) with the minimum cross section of 0.5 up to 0.75 mm2 for
power cables and 0.25 mm2 for signal cables and sensor cables. The cable cross section is given for reference only. The actual conductor
cross-section selection must be based on its type, maximum permissible heating, insulation, length and installation method.
Use copper wires for all the electric connections!
Connect the unit to power mains via the terminal block installed in the power board (A3) in compliance with the wiring diagram and
terminal designation.
Connect the unit to power mains via the terminal block
installed in the power board (A3) in compliance with
the wiring diagram and terminal designation. Connect
the ventilator to power mains through an automatic
circuit breaker with magnetic trip integrated into the
home wiring system. The tripping current of the circuit
breaker is selected based on the electrical characteristics
shown on the label of the fan casing.The ventilator
design enables connecting any external controls with
a normally opened contact (NO contact), such as an
external CO2 sensor, a humidity sensor, a switch, etc.
When the no-contact of the external relay sensor is
closed, the unit changes to the third speed. Upon the
opening of the NO-contact the Boost turn-off delay
timer is activated. When the timer elapses, the ventilator
reverts to the previous speed setting.
*The circuit breaker is not included in the delivery set
and can be ordered separately.
