Installation
Location
The location of the connected equipment
determines the general location of the machine. Motors
and generators, however require large volumes of clean
air for cooling and these machines have environment
requirements which must be considered. They are:
1.
A clean, well-ventilated location.
2.
The machine enclosure should be consistent
with the location, environment and ambient conditions.
3.
If the location is not relatively free of dust and
particles, the machine should have air filters or, in more
severe cases, the machine should be enclosed.
4.
Other equipment, walls, buildings, etc. should
not restrict machine ventilation or allow ventilating air
to recirculate.
5.
Adequate space around the machine for
normal maintenance
6.
Adequate overhead space for removal of the
top cover.
7.
An environment free of corrosive gases and
liquids (both acids and bases).
WARNING:
INSTALLATION OF THE
MACHINE WHERE HAZARDOUS
FLAMMABLE OR COMBUSTIBLE VAPORS
AND/OR DUSTS PRESENT A POSSIBILITY OF
EXPLOSION OR FIRE SHOULD BE IN
ACCORDANCE WITH THE NATIONAL
ELECTRICAL CODE, ARTICLES 500-503, AND
CONSISTENT WITH SOUND LOCAL
PRACTICES. EXTREME CARE IS REQUIRED
FOR MACHINES SUPPLIED WITH A DUST-
IGNITION-PROOF COLLECTOR-RING
HOUSING, ACCESSORY DEVICE, OR
CONDUIT BOX SINCE ANY NICKS OR BURRS
DURING DISASSEMBLY AND REASSEMBLY
MAY DESTROY THE EXPLOSION-PROOF OR
DUST-IGNITION-PROOF FEATURES.
IF IGNITABLE DUST OR LINT IS PRESENT,
THE SURFACE TEMPERATURE OF SPACE
HEATERS, IF SUPPLIED, SHOULD NOT
EXCEED 80 PERCENT OF THE IGNITION
TEMPERATURE. REFER TO FACTORY FOR
INFORMATION ON SURFACE
TEMPERATURE. DUST AND/OR LINT
SHOULD NOT BE ALLOWED TO BUILD UP
AROUND THE SURFACE OF THE SPACE
HEATERS.
FAILURE TO OBSERVE THESE
PRECAUTIONS MAY RESULT IN DAMAGE TO
EQUIPMENT, INJURY TO PERSONNEL, OR
BOTH.
Foundation
The mounting dimensions of the machine and the
minimum foundation stiffness required to adequately
support the machine are supplied on the outline. A
certified outline drawing is supplied by the factory soon
after receipt of the order, and the above information is
essential for planning and constructing the foundation.
A properly constructed foundation is essential to
insure the correct horizontal and vertical alignment of
the driving and the driven equipment, to carry the
weight, to resist the reaction torque, to absorb any
cyclical or dynamical forces generated by the driven
equipment and to prevent vibration amplification. Since
a suitable foundation is a basic requirement for
satisfactory operation, it is recommended that a person
technically competent in foundation design be consulted.
Although adequacy of the foundation is the
responsibility of the owner, the following suggestions are
provided as a guide. A concrete foundation is preferable
to any other type of foundation. It should be reinforced
as required and should extend downward to have a firm
footing. The top of the foundation should be
approximately one inch short of the bottom allow for
grout.
If the machine must be located on structural steel
or on a building floor, the weight and minimum stiffness
requirements stated on the outline drawing must be met.
Also, the dynamics of the entire structural system from
the machine to the structure footing must be considered.
