• Electrical installations must be made by an authori-
zed electrician.
• A wiring diagram is applied on the inside of the junc-
tion box or separately enclosed.
• TKV/TKH 300-400 EC are equipped with a local-
ly situated tension free switcher.
• Electrical installations must be connected to a local-
ly situated tension free switcher or by a lockable
head breaker.
• Control that the fan is installed and connected
electrically in the right way grounded and with a
residual current circuit breaker (type A).
• The fan must be connected to duct before starting.
• When starting make sure that the connecting volta-
ge is in b6% to –10% of the rated voltage
and that no noise appears.
• Make sure that the connection cable is not damage.
• Pay attention to the placement of the connection
cable, to prevent damage when maintaining the fan.
• Regulating the speed can be
done with the built-in poten-
tiometer, 0-10 V. An external
potentiometer can be connec-
ted to the terminal if necess-
ary. The internal potentio-
meter should then
be disconnected.
EMC-COMPATIBLE INSTALLATION
OF EXTERNAL CONTROL LINES
The control cable may not be longer than 60 m. Scree-
ned control cables must be used when the cable length
is longer than 20 m. When using a shielded cable con-
nect the shielding to one side only, i.e. only to the devi-
ce with the protective ground (keep cable short and
with as little inductance as possible!).
Pay attention to suficient distance from powerlines
and motor wires to prevent interferences.

Attention!
Ensure correct polarity!
Never apply line voltage to analog inputs!

When starting the fan, make sure that:
• no noise appears.
• the rated current not exceeds.
• the rotation direction is right,
see the rotation direction label on the fan.
