CONNECTION TO POWER MAINS AND CONTROL
OPERATIONS.
QUALIFIED FOR UNASSISTED OPERATIONS WITH ELECTRICAL INSTALLATIONS UP TO
1000 V AFTER CAREFUL STUDY OF THE PRESENT USER'S MANUAL.
VOID THE WARRANTY.
The ventilator is rated for connection to single-phase ac 100-240 V/ 50-60 Hz power mains.
The routing of the power and signalling cables is shown in Mounting and Set-Up, Page 9.
For electric installations use insulated, durable and heat-resistant electric leads (cables, conductors) with the minimum cross section
0.5 up to 0.75 mm2 for the power cable and 0.25 mm2 for the signalling cables.
The above value is tentative.
The signalling cable must be shielded.
While selecting the required cable cross section consider the cable type, its maximum heating temperature, 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 control circuit in compliance with wiring diagram and terminal
designation.
Connect the unit to power mains via a thermal magnetic circuit breaker, integrated into a house cabling system.
The trip current of the circuit breaker must exceed the ventilator current consumption, refer Table 5.
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 contact NO1 and NO2 closes the ventilator switches to high
speed.
Several ventilators may be in series or parallel connected to power mains
with a central control by the master ventilator.
In case of in-series or parallel connection of several ventilators power is
supplied either from a previous ventilator or from power mains.
