Mechanical installation
Install the FC motor with adequate access for routine
maintenance. Adequate space, particularly at the fan
inlet (50 mm), is necessary to facilitate airflow.
Where several FC motors are installed in close
proximity, care must be taken to ensure that there is
no recirculation of exhausted warm air.

Ambient temperature
To avoid the FC part getting overheated, the
ambient temperature is not to exceed 40 °C
and the 24-hour average temperature is not to exceed
35 °C. If the ambient temperature is in the range of
40 °C - 55 °C, a reduction of the service life of the FC
part is to be expected. For further information, please
see the section on derating in the Design Guide.

Bearings
Ball and roller bearings are despatched from
the works fully charged with grease. Shielded
bearings have sufficient grease for an operating life of
at least two years in normal ambient temperatures,
providing there is little or no leakage.
Tapping of fitments onto the motor shaft,
with a hammer or mallet, causes bearing
damage. This results in increased bearing
noise and a significant reduction in bearing life.

You cannot change the rotation direction of the
motor by shifting around the phases. The
direction of rotation is clockwise by default.
Another direction of rotation can be programmed, see

For terminating an RS 485 interface serial communication,
the bus must be terminated by a resistor network at both

The control cables must be screened cables to ensure

Connect the screen to earth at both ends.
Avoid installation with twisted screen ends (pigtails), since
this ruins the screening effect at high frequencies. Use
cable clamps instead.

Connect mains. LED 302 (green) lights up to indicate
that the power is on. In Profibus versions, LED 303
will flash. For further information on Profibus, please
see the Profibus manual.
Connect terminal 4 and 6 to the start button (see fig.
1).
Connect terminal 2, 7 and 8 to the potentiometer
(see fig. 1).
The voltage on the FC motor is
dangerous when the motor is connected
to mains. Incorrect installation of the FC
motor may lead to material damage or
serious injury or it may be fatal.

Mount the inverter box cover.
Fastening torque: 2.2 - 2.4 Nm
Use the start button to start the FC motor and adjust the
speed by means of the potentiometer.
Motors type B14 & B34 mounting
1) Max length of the fixing bolts / screws
penetrating the B14 flange:
FCM 305-307 (frame 80) =
11.0 mm
FCM 311-315 (frame 90) =
11.5 mm
FCM 322-330 (frame 100) =
15.0 mm
FCM 340 (frame 112) =
15.5 mm
FCM 355-375 (frame 132) =
17.0 mm
2) The following precautions must be taken:
a) A non-setting jointing and sealing
compound must be used to seal the bolt /
screw threads in the motor flange.
b) A soft copper washer must be inserted
underneath the bolt / screw head.
c) The joint face between the motor flange
and the mounting must be sealed using
non-setting jointing and sealing compound.
For B34 types where it is only foot mounted, the flange
is not used. Then the bolts should be fitted in
accordance with parts a) & b) of item 2 to maintain the
IP55.
