This Quick Setup gives information on safety and

helps you to get your FCM 300 Series motors

installed and running in factory setting, see fig. 1. For

additional information, please see the Design Guide.

Before you start, please read the safety instructions

on the back of this Quick Setup.

Mechanical installation

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

cable entries to expose the mains terminals L

Do not lift or remove the entire plastic cover. The

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.

RS 485 switch

For terminating an RS 485 interface serial communication,

the bus must be terminated by a resistor network at both

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:

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.
