SAFETY FIRST

High voltage and rotating parts can cause serious injury or loss of life. Safe installation, operation and maintenance must be performed by qualified personnel. Familiarization with and adherence to NEMA MG2, the National Electrical Code, and local codes is recommended. It is important to observe safety precautions to protect personnel from possible injury. Personnel should be instructed to:

1.Disconnect all power to motor and accessories prior to initiating any maintenance or repairs.

2.Avoid contact with rotating parts.

3.Act with care in accordance with this manual's prescribed procedures in handling and installing this equipment.

4.Be sure unit and accessories are electrically grounded and proper electrical installa- tion wiring and controls are used in accordance with local and national electrical codes. Refer to "National Electrical Code Handbook" - NFPA No. 70. Employ qualified electricians.

5.Be sure equipment is properly enclosed to prevent access by children or other unauthorized personnel in order to prevent possible accidents.

6.Be sure shaft key is fully captive before unit is energized.

7.Provide proper safeguards for personnel against rotating parts and applications in- volving high inertia loads which can cause overspeed.

8.Avoid extended exposure to equipment with high noise levels.

9.Observe good safety habits at all times and use care to avoid injury to yourself or damage to your equipment.

10.Be familiar with the equipment and read all instructions thoroughly before installing or working on equipment.

11.Observe all special instructions attached to the equipment. Remove shipping fixtures if so equipped.

12.Check motor and driven equipment for proper rotation and phase sequence prior to coupling. Also check if a unidirectional motor is supplied and note proper rotation.

13.Do not apply power factor correction capacitors to motors rated for operation

with variable frequently drives. Serious damage to the drive will result if capacitors are placed between the motor and drive. Consult your drive supplier for more information.
