TwinFresh Expert RA/M1-50 (C1) V.3

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 ventilator is rated for connection to single-phase AC 100-240 V 50/60 Hz power mains.
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.
For electric installations use insulated, durable conductors (cables, wires) with the minimum cross section of 0.5 up to 0.75 mm2 for 
a power cable and 0.25 mm2 for signal 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!

External connections diagram

The ventilator design enables connecting any external controls 
with a normally opened contact (NO-contact), such as an external 
CO₂ sensor, humidity sensor, relay switch, etc.
When the normally open contact of the external device is closed, 
the ventilator goes to a maximum speed.

The ventilators can be connected in series and in parallel with a 
central control by the master ventilator.

In case of in series or in parallel connection of several ventilators 
power is supplied either from a previous ventilator or from power 
mains.
