B. Safe Motor Operation Information

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.

F. Relevant Standards

Motors shipped with this installation instruction have
been designed and built to the following standards to
the latest revision:

NEMA MG-1

Motors that have the IECEx designation have also been
designed to meet the requirements of the following
standards:

GEI-56128H

IEC and/or BS/EN 60079-0
IEC and/or BS/EN 60079-15

II. RECEIVING

Each shipment should be carefully inspected upon
arrival. Motor rating and identification data are
furnished on a packing label for verification purposes.
Any damage should be reported promptly to the
carrier and a claim filed. The nearest GE Energy sales
office may provide additional guidance.

A. Unpacking

If the motor has been exposed to low temperatures,
unpack it only after it has reached the temperature of
the room in which it will be unpacked. Otherwise the
motor windings will be exposed to condensing
moisture.

B. Temporary Storage
(Up to 6 Months)

If the motor will not be put into service immediately,
certain precautions should be taken to protect the
motor while in storage. It is recommended the motor
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 windings above the temperature of the
surrounding air. It is recommended the motor in
storage be inspected at periodic intervals, the windings
meggered and a log kept of pertinent data. (Refer to
the 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 machined parts carefully for rust and
moisture and recoat where necessary.

Motors with oil-lubricated or oil-mist lubricated
bearings are normally operated and tested in the
factory with a rust-inhibiting oil in the lubrication
system. A rust-inhibiting film remains on critical
bearing surfaces during transit and for up to six
months in storage. However, when the machine is
received, it is recommended that the bearing oil
reservoirs on sleeve bearing motors be filled to the
proper oil level with a good grade of rust-inhibiting oil.
Rotate the shaft of two-bearing machines (10 to 25
revolutions) until the journals are thoroughly coated
with oil.

5

The bearings of grease-lubricated motors are greased
at the factory with the grease cavity approximately
50% full. Rotate the shaft of all grease-lubricated
motors 10-20 revolutions at two-month intervals.

If the purchaser has specified the machine be
packaged for long-term storage, the foregoing
recommendations do not apply and the packing
should be left intact during the period of storage.

C. Extended Storage

(Longer than 6 months)

In the event the motor is to be stored longer than six
months, please refer to GE instruction manual GEK-

97427.

D. Handling

WARNING: Lifting lugs 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, 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.

III. INSTALLATION

WARNING: Installation should be in

accordance with the ‘USA-National

Electric Code’ or ‘BS/EN 60204-1’ and

‘BS/EN 60204-11’ and consistent with

sound National and local practices.
Coupling, belt and chain guards should be installed
as needed to protect against accidental contact with
moving parts. Motors accessible to personnel
should be further guarded by screening, guard rails,
etc., to prevent them from coming in contact with
the equipment.

A. Location

Install the motor in a well-ventilated area. Make sure
there is a minimum clearance of one foot around the
motor to allow normal flow of air.

1. Dripproof motors are intended to be
used in a well-ventilated place reasonably free of dirt
and moisture.

GEI-56128H

2. General Purpose enclosed motors can
be used where they are exposed to dirt, moisture, and
most outdoor conditions.

3. Severe-duty enclosed motors can be
used in highly corrosive or excessively moist areas.

4. Zone 2 Hazardous Locations

All motors marked with an IECEx or ATEX
designation are suitable for Zone 2 locations. Before
the motor is install in the hazardous location, the
marking must be reviewed for the intended location. If
the motor marking does not meet the intent of the
location do not install or operate the motor. Refer to
BS/EN 60079-0 and BS/EN 60079-15.

Motor marking for IECEx will have a nameplate with
the IECEx logo, IECEx certification number, and IECEx
marking codes. An example of the IEC Ex marking is as
follows;

Ex nA IIC T3 Gc

Where symbol:
a) Ex provides assurance of protection per IEC

standards.
b) nA indicates non-sparking
c) IIC is a code to indicate the type of explosive

gas atmosphere.
d) T3 is a code for the maximum surface

temperature.
e) Gc is a code for the motor protection level.

Refer to B/EN 60079-0 and BS/EN 60079-15 for the
meaning and understanding of all symbols and codes.

5. Division 1 Explosion-proof motors
bearing the Underwriters’ Laboratories label
designating the motor’s Class and Group as defined in
the National Electrical Code (NEC) are designed for
operation in areas classified by local authorities as
hazardous in accordance with the NEC.

B. Mounting

1. Mount motors securely on a firm, flat
base. Grout-in larger motors, if necessary. Grease
lubricated motors can be wall or ceiling mounted with
the shaft horizontal. Grease lubricated motors in NEMA
140–320 frame ratings can be wall mounted with the
shaft vertical. The standard transition and/or sliding
bases are only suitable for floor mounting. For other
mounting positions, please refer to your local GE
representative.

Oil lubricated sleeving-bearing motors shall always be
mounted with the shaft horizontal. The endshield shall
be located with the oil ring sight gage in the twelve
