INDUSTRIAL GENERATOR SETS — APPLICATION & INSTALLATION MANUAL — REV. #4 (09/07/07) — PAGE 35
MOUNTING THE GENERATOR SET
General Information
Generator set installations must be engineered so the
generator set will function properly under the expected load
conditions. Use these instructions as a general guide only.
Follow the instructions of the consulting engineer when
locating or installing any components. The complete
installation must comply with all local, state, and federal
building codes, fire ordinances, and other applicable
regulations.
Always consider the following prior to installation:
z
Level mounting surface
z
Adequate cooling air
z
Adequate fresh induction air
z
Discharge of radiator hot air
z
Discharge of exhaust gases
z
Electrical connections
z
Accessibility for operation and servicing
z
Noise levels
z
Vibration isolation
Location
The generator set location is decided mainly by related
systems such as ventilation, wiring, fuel, and exhaust. The
set should be located as near as possible to the main power
distribution panel.
The generator set should be installed in a protected location
that is guarded against vandalism, theft, and unauthorized
tampering.
Always provide an optimal installation site that is away from
extreme ambient temperatures and that will provide
maximum protection against adverse weather conditions.
Mounting
Mount the generator set on a substantial and level base
such as a concrete pad described previously in the
Foundation section. Provide properly sized mounting bolts
to secure the vibration isolators to the skid using flat or
bevel washers and hexagonal nuts for each bolt. (See Figure
8 below.)
The isolators should be located as shown on the genset
outline drawing.
Vibration Isolators
Steel spring isolators can provide up to 98% reduction in
the force of vibration transmission. Locate the vibration
isolator between the genset skid and foundation in
accordance with the installation drawing. The installation
may require 4, 6, 8, or 12 vibration isolators.

Always consult local air quality
authorities before completing your
construction plans. In most instances,
standby power units must be registered
with the local air pollution control district.
NOTE
NEVER install genset over combustible materials. Locate
genset such that combustible material can not accumulate
under the assembly. The possibility exists of fire or
explosion, causing damage to the equipment and or
severe bodily harm — even death!
Incorrect installation or service can result in severe
personal injury or death, and/or equipment damage. Only
qualified service personnel should be allowed to perform
electrical and mechanical component installation.
