• The fan must be installed according to the air direc-
tion label on the fan.
• The fan must be connected to duct or equipped with
a safety grille.
• The fan should be installed in a safe way and make
sure that no foreign objects are left behind.
• The fan should be installed in a way that makes ser-
vice and maintenance easy. N.B.! Consider the
weight and size of the fan.
• The fan should be installed in a way that vibrations
not can be transfused to duct or building. To provi-
de this, use for example a flange.
• Electrical installations must be made by an authori-
zed electrician.
• See Wiring diagram at the lid of the junction box.
• Electrical installation must be connected to a local-
ly situated isolator switch or by a lockable main
switch.
• Control that the fan is installed and connected elec-
trically in the right way, grounded and with motor
protection.
• For single phase fans a residual current device i used
(type A).
AC-MOTOR
• For speed regulation of AC motor a transformer or
thyristor can be connected.
• The AC motor has a built-in thermal contact.
• The capacitor (only for AC motor) has finite life-
time and should be exchanged after 45.000 opera-
tion hours (about 5 years of operation) to secure
maximum function. Defective capacitor can cause
damage.
EC-MOTOR
• Speed regulating of EC
motor can be done with
the built-in potentio-
meter, 0-10 V.
An external potentio-
meter can be connected
to the terminal if neces-
sary. The internal poten-
tiometer should then
be disconnected.
• Some EC motors has tachometer output one pulse
per revolution.
•
EMC-COMPATIBLE INSTALLATION OF EXTERNAL
CONTROL LINES:
The control cable must not be
longer than 30 m. Screened control cables must
be used when the cable length is longer than
20 m. When using a shielded cable connect the
shielding to one side only, i.e. only to the device
with the protective ground (keep cable short and
with as little inductance as possible!). Pay atten-
tion to sufficient distance from power lines and
motor wires to prevent interferences.
Attention!
Ensure correct polarity! Never apply
line voltage to analog inputs!
• The EC motor has electronically thermal-/over-
voltage protection.
