GEI M1010-A I. 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.
GEI M1010-A C. Safe Motor Operation Information 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.
GEI M1010-A D. Description of Labels and Nameplates Motor rating and identification data are furnished on labels and nameplates. Packing nameplates provide a permanent record of motor characteristics, plant identification and date of manufacture. Below is an example of a label that is attached to the shipping package. MOD – GE model number KW = Motor power rating RPM = Motor speed at full load VOL – Motor voltage ENCL = Enclosure code FR = Frame size MASS = Motor mass Figure 1: Packing Label E.
GEI M1010-A 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.
GEI M1010-A 4. Zone 2 Hazardous Locations All motors marked with an IECEx or ATEX designation are suitable for Zone 2 locations. Before the motor is installed 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.
GEI M1010-A 3. For direct coupled applications use flexible couplings if possible. Accurate mechanical lineup is essential for successful operation. Mechanical vibration and roughness in running the motor may be an indication of poor alignment. In general, lineup by straight edge across, and feeler gauges between coupling halves is not sufficiently accurate. It is recommended that the lineup be checked with a dial indictor and checking bars connected to the motor and load-machine shafts.
1. GEI M1010-A Dry the winding in an air-circulating oven with the air surrounding the winding at 110°C, +5/-15°C until the part has been above 90°C for at least four hours. Then the air temperature may be raised to 150°C, +5°C/-15°C. Continue to heat until the insulation resistance is constant for a one-half-hour period. 2. Enclose the motor with canvas or similar covering, leave a hole at the top for moisture to escape.
GEI M1010-A C. Jogging and Repeated Starts CAUTION: Repeated starts and/or jogs of induction motors greatly reduce the life of the winding insulation. The heat produced by each acceleration or jog is much more than that dissipated by the motor under full load. If it is necessary to repeatedly start or jog a motor, it is advisable to check the application with the local GE Energy sales office. V.
GEI M1010-A E. Vacuum and Compressed Air Cleaning Compressed air should be used to remove loose dirt and dust from air passages such as air ducts. Suction should be used to remove dirt from the windings and to avoid damaging the coils. CAUTION: Care must be taken to make sure the air is dry and that air pressure of not more than 21 x 103kg/m2 (30 psi) is used. WARNING: Operator must not use compressed air to remove dirt or dust from his or her person and clothing. F.
GEI M1010-A The procedure below must be followed for safe and effective re-greasing. The recommended frequency and quantity of grease is stated in tables 5 and 6. WARNING: Lubrication maintenance should be performed with the motor stationary and disconnected from the power source. Extreme caution must be exercised to avoid contact with rotating parts or electrical wiring if the motor must be lubricated while running.
GEI M1010-A VI. OPERATIONAL DIFFICULTIES Some operating difficulties may occur. Common causes are given in Table 2 and should be corrected as soon as possible.
GEI M1010-A VII. FAILURE WARNING: An extreme overload or electrical failure may result in heating or arcing which can cause the insulation to give off noxious fumes. All power should be removed from the motor circuit as a precaution even though the circuit has overload protection. Personnel should not approach the motor until adequate ventilation of the area has purged the air of fumes.
