FCM 300 Series
MG.03.B6.2G - VLT is a registered Danfoss trademark
Handling and lifting of VLT
®
DriveMotors (FCM 300
units) must only be undertaken by qualified personnel.
Full product documentation and operating instructions
must be available together with tools and equipment
necessary for safe working practice. Eyebolts and/or
lifting points supplied with the FCM 300 are designed
to support only the weight of the FCM 300, not the
weight of the FCM 300 and any auxiliary equipment
attached to it. Be absolutely sure that cranes, jacks,
slings and lifting beams are capable of carrying the
weight of equipment to be lifted.
Where an eyebolt is provided with the motor,
■ Handling the FCM 300
this should be screwed down until its shoulder is
firmly against seated the face of the stator frame to be
lifted.

Bearings
To avoid static indention, the storage area should be
vibration free. Where exposure to some vibration is
unavoidable, the shaft should be locked. Bearings
may be fitted with a shaft locking device which
should be kept in place during storage.
Shafts should be rotated by hand, one quarter of a
revolution, at weekly intervals.

NOTE!
Ball and roller bearings are shipped from the factory
fully charged with grease. Sealed bearings have
sufficient grease for at least two years of continuous
operation in normal ambient temperatures (see
General Specifications).
