VLT
®
FCM Series
All operations must be carried out by
appropriately trained personel.
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 "
Special conditions
".
*Note: maximum hand lift is 20 kg below shoulder,
but above ground level. Max. gross weights:
-
Frame size 80: 15 kg
-
Frame size 90 & 100: 30 kg
-
Frame size 112: 45 kg
-
Frame size 132: 80 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 manual
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.
- 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 VLT DriveMotor (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.
Use of RCD
’
s (ELCB relays) is described
in chapter 10.
3. The earth leakage currents are higher than 3.5
mA. This means that the FC motor requires
a fixed, permanent installation as well as
reinforced protective earthing.
■
Warning against unintended start
1. The motor can be brought to a stop by means of
digital commands, bus commands, or references,
while the frequency converter 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 mains supply ceases.
