If you install the product near a duct bend, do these
steps to prevent vibrations, unwanted noise and de-
creased air pressure:

a.

Measure the distance (A) between the product and
the duct bend.

b.

Make sure that the distance (A) is a minimum of 2.5
x the diameter (B) of the duct system. For circular
ducts, (B) is the nominal diameter. For rectangular
ducts, (B) is the hydraulic diameter.

Electrical connection

5.1

To do before the electrical
connection

• Make sure that the electrical connection agrees with the

product specification on the motor name plate.

• Make sure that the environment for electrical connection

is clean and dry.

• Make sure that the wiring diagram that is included with the

supply of the product agrees with the terminals in the con-
nection box.

5.2

To connect the product to the
power supply

• Complete the electrical connection for the motor. Refer to

the motor wiring diagram that is included with the product.

• Make sure that the cross section of the protective earthing

is equal to or larger than the cross section of the phase
conductor.

• Install a circuit breaker in the permanent electrical installa-

tion, with a contact opening of a minimum 3 mm at each
pole.

• If a residual current device (RCD) is installed, make sure

that it is an all-current sensitive RCD. Consider if the prod-
uct has a frequency converter, uninterruptible power sup-
ply (UPS), or an EC motor. EC motors have a leakage
current to earth that is <=3.5 mA.

5.3

Speed controller for EC
motors

• EC motors are controlled through a stepless 0–10 V signal.

• Do not use power supply for the speed controller.

• Refer to

12.3 Wiring diagrams page 14

and the instruction

manual for the external speed controller.

5.4

Motor protection for EC
motors

EC motors have an integrated motor protection. Reset the
motor protection by disconnecting the fan from power supply
for 60 seconds.

5.5

Speed controller for AC
motors

Note:

The speed controller alternatives are different for different
motor types. Make sure that your motor is compatible with
the speed controller type before you use it.

The speed can be controlled by voltage reduction using a
transformer. It is also possible to control the fan speed with
frequency converter if the installed frequency converter has
built in all-pole sine filter and shielded cables are not needed.
