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).

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.
Mounting
The machine has two full-length mounting feet,
one on each side, consisting of machined steel bars
