CONNECTION TO POWER MAINS

The ventilator is rated for connection to single-phase ac 1~100-230 V / 50-60 Hz power mains. For wireworks facilitation, the ventilator is
supplied with a pre-wired power cord and a plug.
Connect the ventilator to power mains through the automatic circuit breaker with magnetic trip integrated into the fi xed wiring system.
When the ventilators are connected in series, all the connected ventilators are controlled with the fi rst ventilator and a common
remote control. To connect the ventilators in series connect the Output contact socket of the fi rst ventilator mounting plate with the
Input contact socket of the second ventilator mounting plate.
Connect the second ventilator with the third ventilator in the same way, etc. Up to 10 ventilators may be connected in series.
For easy electric installations use a fi ve-wire cable (not included into the delivery set) with the cable cross section not below 0.5 mm
The cable must be rated for operation in an alternating current power supply with the country-specifi c mains voltage. Disconnect the
power cord while connecting the second, third, etc. ventilator in series.
TO THE NEXT
VENTILATOR
The fi rst ventilator controls all the connected ventilators.
The jumper between the contacts 1 and 2 or 2 and 3 of CN7
socket connector determines a fl ow direction in Ventilation mode.
If the jumper connects the contacts 1 and 2, air is extracted
from the room in Ventilation mode (factory setting).
If the jumper connects the contacts 2 and 3, air is supplied
in Ventilation mode.
The jumper position at each connected in series ventilator
determines a rotation direction in Ventilation mode and an
operating phase in Regeneration mode. I.e. if the jumper at the
fi rst ventilator connects the contacts 2 and 3 and the jumper at the
second ventilator connects the contacts 1 and 2, the ventilators
operate in opposite directions in Regeneration mode.
DISCONNECT THE VENTILATOR FROM POWER MAINS PRIOR TO ANY
ELECTRIC INSTALLATION OPERATIONS. CONNECT THE VENTILATOR TO
A CORRECT INSTALLED SOCKET WITH A GROUNDED TERMINAL. ANY
INTERNAL CONNECTION MODIFICATIONS ARE NOT ALLOWED AND RESULT
IN WARRANTY LOSS.
