Introduction

These instructions present general recommendations forinstallation, operation and maintenance of verticalinduction motors built at the Norwood Plant. If additionalinformation is required, contact the Siemens IndustrialProducts Division.

WarrantySee your sales contract for warranty coverage.Documentation of storage maintenance, alignment andregreasing may be required for certain warrantyconsiderations.

ReceivingMotors are shipped in first class condition. They havebeen inspected and are blocked or crated to preventdamage from ordinary handling during shipment.

Inspect new motors for shipping damage when received.Make the examination before removing from cars ortrucks. If damage or indication of rough handling isevident, file a claim with the carrier at once, and notify yourSiemens customer service representative at Norwood,Ohio.

Remove only the shipping invoice. Do not remove tagspertaining to lubrication, operation, and storageinstructions. Read and follow all instructions to insure thatno damage to motor bearings, (due to condensation) andmotor windings occurs during storage.

Use care in handling. Dropping the motor or otherwiseimposing shock loads can cause unseen and undetecteddamage to bearings. This damage such as false brinellingof the races of anti-friction bearings can result in earlybearing failure.

If supplied, energize space heaters to help preventcondensation within the enc
