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.

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.

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.

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.
