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.

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.
