Introduction

DANGER

Hazardous voltage.

Will cause death, serious injury,

electrocution or property damage.

Disconnect all power before working on

this equipment.

These instructions present general recommendations

for installation, operation and maintenance of

induction motors built at the Norwood plant. If

additional information is required, contact Siemens

Industry.

Warranty

See your sales contract for warranty coverage.

Documentation of storage maintenance, alignment

and regreasing may be required for certain warranty

considerations.

Receiving

Motors are shipped in first class condition. They have

been inspected and are skidded to prevent damage

from ordinary handling during shipment.

Inspect new motors for shipping invoice. Make the

examination before removing from cars or trucks. If

damage or indication of rough handling is evident, file

a claim with the carrier at once, and notify your

Siemens sales representative.

Remove only the shipping invoice. Do not remove

tags pertaining to lubrication, operation and storage

instructions. Read and follow all instructions to insure

that no damage to motor bearings, (due to

condensation) and motor windings occurs during

storage.

Use care in handling. Dropping the motor or

otherwise imposing shock loads can cause unseen

and undetected damage to bearings. This damage

such as false brinelling of the races of anti-friction

bearings can result in early bearing failure.

If supplied, energize space heaters to help prevent

condensation within the motor enclosure.

Motors having sleeve bearings or oil lubricated

antifriction bearings are shipped WITHOUT OIL in the

bearing reservoir. These bearings and journal

surfaces are protected during shipment by a

temporary film of rust inhibiting oil or, when a motor is

supplied specifically with “provisions for oil mist

lubrication” (oil supply system furnished by the user),

the motor is shipped from the factory with grease in

the bearings.

When receiving a motor with sleeve bearings:

1. Remove shaft blocking materials.

2. Visually inspect bearing condition through sight

glass and bearing drain opening.

3. Check for moisture accumulation. Remove any

traces of oxidation before putting the motor into

service.

4. Fill bearing reservoirs to normal level with a high

grade industrial lubricating oil. See Maintenance

Section of this instruction book to determine

proper oil level.

5. Rotate the shaft a minimum of 10 complete turns

by hand to distribute oil over bearing parts. Make

sure the oil rings in each bearing rotate freely.

When receiving a motor with grease lubricated

anti-friction bearings:

Motors having grease lubricated antifriction bearings

are shipped with the bearings already lubricated and

ready for operation.

If the elapsed time from the time of shipment to the

time in which the unit is to be started is in excess of

thirty (30) days, regrease per the lubrication plate

mounted on the motor.

When receiving a motor with oil mist lubricated

anti-friction bearings:

1. Be sure that the motor is not stored outdoors.

2. Be sure that the oil mist lubrication is connected

and operating before starting the motor.

3. The oil mist lubrication should be in operation

within two weeks after the motor is received from

the factory.

When receiving a motor with “provisions for oil

mist lubrication”:

1. Leave the grease in the bearings if the motor is to

be stored.

2. Before operating the motor with oil mist

lubrication, disassemble the motor, and clean the

grease from bearings, end caps, and the bearing

housing cavities with a suitable solvent.
