Installation of the FC motor
FC motors must be installed with adequate access for
routine maintenance. A minimum of 0.75m of working
space around the motor is recommended. Adequate
space around the motor, particularly at the fan inlet (50
mm), is also necessary to facilitate airflow.
Where several FC motors are installed in close prox-
imity, care must be taken to ensure that there is no
recirculation of exhausted warm air. Foundations must
be solid, rigid and level.
NB!
Electrical installation
Do not remove the top foil inside the in-
verter part, as this is a part of the protec-
tive arrangements.
Fitting pinions, pulleys and couplings.
These should be bored to our standard limits and fitted
on the shaft with a screwing motion. Attention must be
paid to correct guarding of all moving parts.
Tapping of fitments onto the FC motor
shaft, with a hammer or mallet, causes
bearing damage. This results in an in-
crease in bearing noise and a significant
reduction in bearing life.
NB!
Max. length of mounting bolts penetrating
the B14 flange, see section Dimensions in
this chapter.
Alignment
When the application calls for direct coupling, the
shafts must be correctly aligned in all three planes.
Bad alignment can be a major source of noise and vi-
bration.
Allowance must be made for shaft endfloat and ther-
mal expansion in both axial and vertical planes. It is
preferable to use flexible drive couplings.
