NB!:
Do not lift or remove the entire plastic cover.
The voltage on the FC motor is dangerous
and may lead to material damage, serious
injury or it may be fatal.

Make sure that your mains supply corresponds
to the voltage required by the FC motor (see
inverter label), TT and NT mains .
Connect the three mains phases to terminals L

Fixed wires:
Rated temperature for fixed wires min. 60° C or 140° F.
Use copper conduction only.
NB!:
You cannot change the rotation direction of the
motor by shifting around the phases. The direct-
ion of rotation is clockwise by default. Another
direction of rotation can be programmed, see the Design
Guide.

Type gG prefuses must be used. If you want to maintain
UL/cUL you must use prefuses of the type Bussmann 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 V maximum.

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:
LED 300 (red):
Fault trip
LED 301 (yellow):
Warning
LED 302 (green):
Power on
LED 303-304 (green): Communication
EMC-correct 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.
3 Start the FC motor
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).
Use the start button to start the FC motor and adjust the
speed by means of the potentiometer.
