EC motors
Fig. 5 shows the electrical connections for each
versions of single phase motors. Vortice suggest the
use of the optional potentiometer (not supplied):
Cod.12.828 - POT
NOTE:
• The installer is responsible for connecting optional
safety devices that automatically turn the appliance
OFF when the inspection panel is opened. The
installation of micro-switches, like any other
electrical safety device fitted, must completely stop
the appliance from operating. Should this happen,
the power supply to appliance can only be restored
by manually turning the appliance switch back ON
and by returning power to it from the mains board.
• The installer is responsible for activating any safety
devices on the appliance in accordance with the EC
Machinery Directive.
• All the wiring and electrical components used in the
installation must comply with current European and
local legal requirements.
• All the QBK motors have, internally, a thermal
protection (see “Maintenance and cleaning”).
Voltage and frequency
The motor feeding connection must be done
according to the tension and frequency indicated in
the fan’s plate. Some differences (±5%) can be
allowed in the power circuit. If the connection cannot
keep this level there is a high risk of burning the motor.
Therefore, ensure the selected disposition of Y-1
corresponds to the tension of the power circuit and
use a tester to check besides the tension the
frequency as well.
Consuption
Control that the consumption (A) once installed in the
fan does not exceed the conditions specified in the
fan’s plate. The capacity of the fan and the installation
charge should be correctly adjusted (see “Start up”).
In case of non compliance please consult the
manufacturer.
Ground system
According to the current legislations the fan is a Class
I and it is mandatory that the ground system is
connected, it can be found inside the connection box
of the motor or the fan.
The earth connection must be made using the
special terminals inside the appliance and in
complete accordance with current legal
requirements.
Once connected, it is advised to check the electric
insulation with device (tester).
Environment conditions
The following environment conditions need to be
respected:
- Temperature = 40°C Max;
- Relative humidity = 60% Max.
In case of doubts, checking the rating label of the
product is always advised: it contains all the technical
informations to be respected.
Note: Motorfans insulation class is F.
for other applications, who needs particular features,
checking technical data is always advised. In case of
doubts of more informations: contact the supplier
directly.
Direction of the rotation
The direction of the rotation is shown into the housing
(see: “Electrical connections”).
