GENERAL INFORMATION

A. How to Properly Use this Instruction Manual
This installation and maintenance manual has been written to assist the user with proper procedures when
handling, installing, operating and maintaining the equipment. All of the safety warnings and instructions in
this book must be followed to prevent injury to personnel.
This manual must be kept for future reference during installation, operation and maintenance.
B. Safe Motor Operation Information
WARNINGS:
personnel should perform installation, operation and maintenance of electrical machinery. For
equipment covered by this instruction book, it is important to observe safety precautions to
protect personnel from possible injury. Be sure to keep the installation and maintenance information for future
reference. All warnings and cautions must be followed.
Installation
Avoid contact with energized circuits and rotating parts.
Avoid bypassing or rendering inoperative any safeguards or protective devices.
Avoid use of automatic-reset thermal protection where unexpected starting of equipment might be
hazardous to personnel.
Avoid contact with capacitors until safe discharge procedures have been followed.
Be sure the motor shaft key is captive before the motor is energized.
Avoid long exposure in close proximity to machinery with high noise levels.
When the motor is coupled to equipment, ensure that system vibrations are within acceptable limit (per ISO
10816-1) to avoid failure of the motor.
Use proper protective gear, care and procedures when handling, lifting, installing, operating and
maintaining the motor.
If eyebolts are used for lifting motors, they must be securely tightened, and the direction of the lift must not
exceed a 15° angle from the shank of the eyebolt. Do not use eyebolts in an ambient below 0°F. At
temperatures below 0° F, the eyebolt could fail resulting in injury to personnel and/or damage to equipment.
Drop-forged eyebolts per American Society of Testing Materials A489 or equivalent must be used.
Do not use the motor shaft as a means for lifting.
Do not lift both the motor and driven equipment with the motor lifting means.
Do not stand on or place objects on the motor.
Maintenance
Safe maintenance practices performed by qualified personnel are imperative. Before starting maintenance
procedures, be positive that:
Equipment connected to the shaft will not cause mechanical rotation.
Main motor windings and all accessory devices associated with the work area are disconnected from
electrical power sources.
The motor has been given time to cool.
Failure to properly ground the frame of the motor can cause serious injury to personnel. Grounding should be in accordance with National and
local Standards and consistent with sound practice.
These instructions do not purport to cover all the details in motors nor to provide for every possible contingency to be met in connection with
installation, operation or maintenance. Should further information be desired or should particular problems arise which are not covered
sufficiently for the purchaser's purposes, the matter should be referred to the General Electric Company.
