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 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 through the external
circuit breaker with a magnetic trip integrated into the
fixed wiring system. The tripping current of the circuit
breaker is selected based on the electrical characteris-
tics 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 device is closed,
the unit changes to the maximum speed.
An analogue sensor with output voltage 0-10 V is also
compatible with the unit.
*The circuit breaker is not included in the delivery set.
