Warning
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.
4 Mount the inverter box cover.
Fastening torque: 2.2 - 2.4 Nm
Safety Safety Safety Safety Safety
All operations must be carried out by
appropriately trained personnel.
Use all lifting facilities provided e.g. both
lifting points, if fitted, or single lifting point, if
fitted*.
Vertical lifting - Prevent uncontrolled rotation.
Lift machine - Do not lift other equipment with motor
lifting points only.
Before installation check for fan cover damage, shaft
damage, foot/mounting damage, and loose
fasteners. Check nameplate details.
Ensure level mounting surface, balanced mounting,
not misaligned.
Gaskets, and/or sealants, and guards must be
correctly fitted.
Correct belt tension.
Please observe derating rules, see Design Guide
* Note: maximum hand lift is 20 kg below shoulder, but
above ground level.
Max. weights:
- Frame size 80: 15 kg
- Frame size 90 & 100: 30 kg
- Frame size 112: 65 kg
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.
Consequently, the instructions in this Quick Setup as
well as national and local rules and safety regulations
must be complied with.
Touching the electrical parts may be fatal, even after the
mains supply has been disconnected.
Wait at least 4 minutes.

VLT ® DriveMotor FCM 300 Quick Setup
■ Warning against unintended start
- Installation must be fused and isolated correctly.
- Covers and cable entries must be fitted
NB!:
It is the user's or certified electrician's
responsibility to ensure correct earthing and
protection in accordance with applicable national
and local requirements and standards.
Safety regulations
1. The FC motor must be disconnected from mains if
repair work is to be carried out. Check that the mains
supply has been disconnected and that the
necessary time has passed (4 minutes).
2. Correct protective earthing of the equipment must be
established, the user must be protected against
supply voltage, and the motor must be protected
against overload in accordance with applicable
national and local regulations.
In UL/cUL applications ETR provides class 20,
overload protection in accordance with the NEC
RCD's (ELCB relays), multiple protective earthing or
earthing can be used as extra protection, provided
that local safety regulations are complied with.
In case of an earth fault, a DC content may develop
in the fault current.
If RCD's are used, local regulations must be
observed. Relays must be suitable for protection of
3-phase equipment with a bridge rectifier and for a
brief discharge on power-up.
3. The earth leakage currents are higher than 3.5 mA
(approx. 7 mA). This means that the FC motor
requires a fixed, permanent installation as well as
reinforced protective earthing.
1. The motor can be brought to a stop by means of
digital commands, bus commands, or references,
while the FC motor is connected to mains. If personal
safety considerations make it necessary to ensure
that no unintended start occurs, these stop functions
are not sufficient.
2. While parameters are being changed, the motor may
start.
3. A motor that has been stopped may start if faults
occur in the electronics of the FC motor, or if a
temporary overload or a fault in the supply mains or
the motor connection ceases.
