Introduction
WARNING
Heavy equipment.
Improper handling may cause death, serious injury or
property damage.
Check lifting devices before lifting. Use proper slings,
chains and spreaders.
Note any warning plates on motor and follow
instructions on each plate.
Handling
Lifting devices are provided for handling only. An
experienced rigger should be used to install motors.
To avoid damage, the use of spreader bars is
recommended on other than single point lifts. Lifting
devices are provided to facilitate handling with
shackles and cables. Avoid pounding or bumping
shaft, coupling or bearing parts, as shocks may
damage bearings.
NOTE WEIGHT BEFORE LIFTING. The weight is
indicated on the outline drawing. Apply tension
gradually to cables. Do not jerk or attempt to move the
unit suddenly.
Motor Weights (in pounds)

580 4600 6700
708 8200 9900
788 11500 13700
880 15800 19700
Temporary Storage
If the equipment is not to be installed and operated
soon after arrival, store it in a clean, dry, well-
ventilated place, free from vibration and rapid or wide
variations in temperature. Rotate the shaft a minimum
of 10 complete turns by hand each month to coat the
bearings with lubricant which will retard oxidation or
corrosion, and prevent possible false brinelling. If drain
plugs are provided in enclosed motors, they must be
removed periodically to drain any water accumulation
from the motor. Consider a unit in storage when:
1. It has been delivered to the job site and is awaiting
installation.
2. It has been installed but operation is delayed over
30 days pending completion of plant construction.
3. There are long (30 day) periods between operating
cycles.
4. The plant (or department) is shut down for 30 days.
NOTE
Storage requirements vary, depending on the length of
storage and the climate. For storage periods of three
months or longer or climate variations, consult Siemens
Storage Recommendations ANIM-03114. Storage
maintenance is to be documented for warranty
information.
Type Designations
The motor type designation consists of a basic letter or
letters indicating the motor enclosure type to which
other letters may be added denoting modifications.
