The fan has two speeds. Depending on the required fan performance, the phase of the power supply is switched between
the terminals:
For models with flange diameter from 100mm to 315mm
• L1 Low Speed
• L2 High Speed
When setting a high fan speed, depending on the model, it is necessary to connect the fan as follows: L2 (phase of the
supply network), N (neutral of the supply network), protective earth (for models 250, 315).
When setting a low fan speed, it is necessary to switch the phase of the supply network from terminal blocks L2 (phase)
to terminal blocks L1 (phase), connection N (neutral of the supply network), the protective ground remains unchanged (for
models 250, 315).
ATTENTION! In order to avoid damage to the fan, do not simultaneously connect a phase of the supply mains to
terminals L1 and L2.
ATTENTION! All work on installation and connection of fans should be carried out only with the mains voltage
removed.
The fans shall be connected by electricians who have a special permit for the work performed.
Means for disconnecting from the mains supply should be built into the fixed wiring, in accordance with the installation
regulations. The disconnecting device should disconnect all poles. The grounding conductor should not break.
The fan and auxiliary control equipment should be isolated from the power supply during installation and/or maintenance.
The equipment should be grounded (for 250, 315 models).
Please remove the cover from the terminal box, study the wiring diagram (Fig. 2 or Fig. 3), and make the necessary
connections. Check whether a ground connection exists (for 250, 315 models).
After finishing the connection work and checking the connections to the terminal box, move the cover and make sure it is
fixed.
Installation: The length of the firmly installed piping from the fan should be at least 500mm on each side.
When connecting TYPHOON fan with IP44, it is required to pass a network cable with a diameter of at least 4 mm through
a cable gland.
The cable gland is designed for sealed input-output of cables from wires in switchboard enclosures.
The compression nut design has special locking notches to prevent self-loosening. A protective diaphragm
prevents dust from entering the enclosure and achieves a degree of protection IP44 and above.
Malfunction
When connected to the mains, the
fan does not rotate, it does not
respond to controls.
Low air consumption.
Increased noise or vibration.
Burning odor.
ATTENTION! The fan and auxiliary control equipment should be isolated from the power supply during
installation and/or maintenance. The equipment should be grounded (for 250, 315 models).
