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 CO
2
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.
Switch off before any work with the appliance.
The appliance must be connected to the electrical network by a qualified electrician. The
electrical parameters of the device can be found at manufacturer's labels.
Any modification of the internal circuit is prohibited it will revoke the warranty.
