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.

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.

Electrical connections

Remove the inverter box cover, which is held by four

screws, to obtain access to the terminals.

Remove the detachable terminal plugs from the

terminal blocks X100 and X101 to obtain access to

the mains terminals.

Lift only the corner of the black plastic cover by the

You cannot change the rotation direction of the

motor by shifting around the phases. The

direction of rotation is clockwise by default.

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.

Motors type B14 & B34 mounting

1) Max length of the fixing bolts / screws

penetrating the B14 flange:

FCM 305-307 (frame 80) =

FCM 311-315 (frame 90) =

FCM 322-330 (frame 100) =

FCM 340 (frame 112) =

FCM 355-375 (frame 132) =

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.

KTS-R 500 V or Ferraz Shawmut, type ATMR (max. 30A). The

fuses must be placed for protection in a circuit that is capable of

supplying a maximum of 100,000 amps RMS (symmetrical), 500

RS 485 switch

For terminating an RS 485 interface serial communication,

the bus must be terminated by a resistor network at both

and

ends. This is provided by setting both switches to ON.

LEDs

The FC motor has five LEDs which indicate the status of

the FC motor:

LED 300 (red):

LED 301 (yellow):

EMC-correct installation

EMC-corr

ect installation

The control cables must be screened cables to ensure

EMC-correct electrical installation.

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.

Use the start button to start the FC motor and adjust the

speed by means of the potentiometer.

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.
