I. GENERAL INFORMATION
This 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.
The installation and maintenance manual must be kept for future reference during installation, operation and
maintenance.
The use of a lightning bolt within an
arrowhead symbol, enclosed in a
yellow triangle, indicates warning of
dangerous electrical voltage that could
cause an electric shock to a person.
The use of an exclamation point within
a yellow triangle indicates to the user
that important installation operating
and maintenance instructions must be
followed.
This symbol identifies any terminal
which is intended for connection to
an external grounding conductor for
protection against electric shock in
case of a fault.
The use of a small case “i” enclosed
in a square indicates a general note.
CAUTION:
Indicates a procedure or condition
that, if not strictly observed, could
result in minor injuries to personnel.
WARNING:
Indicates a procedure or condition
that, if not strictly observed, could
result in personal injuries or death.

B. Safety Symbol Legend
Below is a safety symbol table that identifies the safety symbols that appear in this manual
and on the equipment.

I. GENERAL INFORMATION (cont’d)
WARNINGS: High voltage and rotating parts can cause serious or fatal injuries. Qualified
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 shaft key is captive before the motor is energized.
Avoid long exposure in close proximity to machinery with high noise levels.
Use proper care and procedures in handling, lifting, operating and maintaining the equipment.
Use proper protective gear when handling, lifting, installing, operating and maintaining the equipment.
If eyebolts are used for lifting motors, they must be securely tightened, and the direction of the lift must
not exceed a 15 angle with the shank of the eyebolt. Do not use eyebolts in an ambient below 0F. At
lower temperature, 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 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 the National Electrical Code and consistent with sound practice.
These instructions do not purport to cover all details in equipment 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.
This document contains proprietary information of General Electric Company, USA and is furnished to its
customer solely to assist that customer in the installation, testing, operating and/or maintenance of the
equipment described. This document shall not be reproduced in whole or in part, nor shall its contents be
disclosed to any third party without the written approval of GE Energy.

II. RECEIVING, STORAGE, HANDLING AND UNPACKING
Warning
The lifting lugs or eyebolts on the motor are designed for handling only the motor. They are not
to be used to lift the motor plus additional equipment such as pumps, compressors, or other
driven equipment. In the case of assemblies on a common base, the lugs or eyebolts provided on
the motor are not to be used to lift the assembly and base. The assembly should be lifted by a sling around
the base or by other lifting means provided on the base. In the case of unbalanced loads (such as couplings or
other attachments), additional slings, or other effective means should be used to prevent tipping. Failure to
observe these precautions may result in damage to the equipment, injury to personnel, or both.
A. Receiving
Each shipment should be carefully inspected upon arrival. Any damage should be reported
promptly to the carrier and a claim filed. The nearest GE sales office can provide additional
guidance.
B. Storage
If the machine will not be put into service immediately, certain precautions should be taken
to protect the machine while in storage. It is recommended that the machine be placed
under cover in a clean, dry location.
During storage, windings should be protected from excessive moisture by some safe and
reliable method of heating, such as space heaters, to keep the temperature of the
windings a few degrees above the temperature of the surrounding air. It is recommended
that the machine be inspected at periodic intervals, the windings meggered, and a log kept
of pertinent data. (Refer to Operation section.) Any significant drop in insulation resistance
should be investigated.
Precautions are taken by the factory to guard against corrosion. The machined parts are
coated to prevent rust during shipment. If the equipment is to be stored, examine the parts
carefully for rust and moisture and re-coat where necessary.
Grease-lubricated machines have the bearings greased at the factory with the cavity
approximately 50% full.
Rotate the shaft of all two-bearing machines 10-20 revolutions at two-month intervals.
C. Handling
Before lifting the motor, ensure that the eyebolt shoulder is completely seated against the
motor frame boss. Eyebolt should only be tightened by hand.
The angle of lift must not exceed a 15o angle with the shank of the eyebolt.

C. Handling (cont’d)
D. Unpacking
If the machine or machine parts have been exposed to low temperatures, unpack it only
after it has reached the temperature of the room in which it will be unpacked or located
condensation will occur.
E. Description of Labels and Nameplates
Motor rating and identification data are furnished on labels and nameplates. Labels
provide basic motor characteristics. Nameplates provide a permanent record of motor
characteristics, plant identification and date of manufacture.
F. Model and Serial Numbers
As discussed in section E, every motor that is manufactured by GE is provided with a model
and serial number which is permanently marked on the motor nameplate and shipping
pack. These numbers identify basic motor characteristics and pertinent data. When
contacting a GE Service Shop or representative, please refer to the model and serial
number.
