INSTALLATION & OPERATION

INTRODUCTION

THIS EQUIPMENT CONTAINS HAZARDOUS VOLTAGES, ROTATING PARTS AND HOT SURFACES. SEVERE PERSONAL INJURY OR PROPERTY DAM- AGE CAN RESULT IF SAFETY INSTRUCTIONS ARE NOT FOL- LOWED. ONLY QUALIFIED PER- SONNEL SHOULD WORK ON OR AROUND THIS EQUIPMENT AFTER BECOMING THOR-

INSPECTION

Care is taken at the factory to assure that the motor arrives at its destination in first class condition. If there is evidence of rough handling or damage in shipping, file a claim at once with the carrier and notify your Siemens Sales Office.

Examine the outside of the motor carefully for damage, with particular attention to conduit box, fans, and

covers. Inspect and tighten all hard- ware and accessories, which may have become loosened during ship- ping and handling. Turn the shaft by hand to be sure that it rotates freely. If the motor has been mis- handled sufficiently to break exter- nal parts, the end shield should also be removed to check for internal damage unless the motor is explo- sion proof. See warning below on explosion proof motors.

OUGHLY FAMILIAR WITH ALL WARNINGS, SAFETY NOTICES, AND MAINTENANCE PROCE- DURES CONTAINED HEREIN. THE SUCCESSFUL AND SAFE OPERATION OF THIS EQUIP- MENT IS DEPENDENT UPON PROPER HANDLING, INSTALLA- TION, OPERATION AND MAIN- TENANCE.

WARNING

Explosion.

Can cause death, serious injury or property damage.

When repairing and reassembling a motor that has an under- writer’s label, it is imperative that the unit be re-inspected and:

1All original fits and tolerances are maintained.

2All plugs and hardware be securely fastened.

3Any parts replacements, including hardware, be accurate duplicates of the Originals.

Repair work on explosion proof-motors can only be performed by the original manufacturer or U.L. certified shops. Violations of any of the above items will invalidate the significance of the U.L. Label.

STORAGE

Motors must be stored in a clean, dry, well ventilated location free from vibration and rapid or wide temperature variations. If the unit is to be stored longer than three months, consult the factory. Ball bearing motors are shipped from the factory properly lubricated and ready to operate. When in storage, the motor shaft must be turned several rotations every month and the bearing re-lubricated every year. On non-explosion-proof TEFC motors, a removable plug in the bottom of the frame or housing per- mits removal of accumulated mois-

ture. Drain regularly if storage atmosphere results in formation of condensation.

INSTALLATION

Qualified service or maintenance personnel must handle installation, The motor foundation must rigidly support all four feet in the same plane. Place shims under the motor feet, as required; so they will not be pulled out of plane when mount- ing bolts are tightened. All wiring to the motor and control must be in accordance with the National Electrical Code and all local regula- tions. Before load is connected,

momentarily energize motor to check that the direction of rotation is proper. For direct connected loads, accurate alignment is 0.004 inch/ft. (Radius to dial Indicator = one foot)

Any change in shims requires re- checking alignment. When align- ment is within limits, dowel two feet of each unit. When installing V-belt sheave, spur or helical pinion or chain drives, be certain that they are within NEMA limitations. Refer to NEMA motor and general stan- dards, MG1-14.07 and 14.41.
