Installation and commissioning

8
DANGER
1.- The installation, operation and maintenance of the motor shall be
carried out by qualified personnel, who must be familiar with codes,
guidelines and applicable local regulations. Personnel must use the
adequate tools and be experienced in installation, operation and
maintenance of electric motor.
2.- Before any handling, make sure you have your personal safety
equipment such as shoes, gloves, girdle and lenses because if these
preventive measures are not taken, physical damage may occur.
3.- When working with voltage levels up to 600 V.A.C. and moving parts
(even at low speeds) there is the possibility to suffer serious injuries or
death. Before any repair or maintenance service, use electrical or
mechanical locks to prevent a sudden or unwanted startup of the motor.
CAUTION:
1.- The motor shall be installed in an environment adequate for its design
and application features. Otherwise, the motor will have a deficient
performance and a reduced life. For further information please consult your
local SIEMENS sales office.
2.- The motor foundation must rigidly support (Screwed) all four feet in the
same plane in order to avoid vibrations and maintain a correct alignment
between the motor shaft and the load. Shims can be used under the motor
feet. For direct drive, accurate alignment is 0.004 inch/ft. (radius to dial
indicator = one foot). Any change in shims requires rechecking alignment.
3.- When installing flat belt pulley, V-belt sheave, spur or helical pinion or
chain drives, be certain that they are within NEMA-MG1 limitations. Refer to
NEMA-MG1, Section II part 14.7 and Section II part 14.42. Protective
covers must be installed to prevent unwanted contact between moving
parts and other objects or personnel.
4.- Ensure that any optional supplementary motor monitoring equipment
has been connected correctly and is functioning as it should.
5.- It ensures a long life of the bearings maintaining proper alignment,
adequate tension in the band or chain and good lubrication at all times.
6.- Ensure that the cooling airflow is not obstructed or diminished in any
way and have enough free space for the correct operation of the motor.
7.- Prevent the air expelled by neighboring equipment from being
immediately sucked in again.
8.- For motors with a vertical type construction with air entry from above,
prevent the ingress of foreign bodies and water in the air entry openings.
