6.1.3 SUSPENDED MOUNTING
If you are going to suspend the generator below the
horizontal support tubing, the suspension method
you use with the vehicle frame members must (a) be
able to support the weight of the generator AND (b)
provide sufficient restraint for the generator. One typ-
ical suspended mounting system is shown in Figure
6.2. The location of a suspended mounting system
must be carefully planned, keeping the following gen-
eral rules in mind:
• Protect the generator against road splash and debris.
Baffles or splash guards may be required to protect
certain areas of the generator. To make sure the gen-
erator is adequately protected, road test the installa-
tion through mud, water and slush.
Figure 6.2 – Typical Suspended Mounting System
• The installer must make certain that the selected
location will permit adequate cooling and ventilat-
ing airflow to be supplied.
6.1.4 GENERATOR RESTRAINT
Use four 3/8"-16 hardened steel bolts (Grade 5) to fas-
ten the generator to the supporting frame or the sup-
port tubing. These bolts must pass through (a) the gen-
erator mounting base, (b) the compartment floor (if a
compartment is used) and (c) the supporting frame-
work (Figure 6.3). All bolts must be long enough so that
when tight, at least three threads are visible past the
retaining lock nuts. Refer to Section 6.2 for the location
of the generator mounting holes.

6.2 GENERATOR COMPARTMENTS
Whether the generator set is being installed inside a
compartment specifically manufactured to house a gen-
erator or inside a compartment that the installer con-
structs, the compartment MUST meet certain specifi-
cations as outlined in the following sections:
6.2.1 COMPARTMENT SIZE
Plan the compartment size carefully. Provide a mini-
mum clearance of 1/2 inch (13 mm) on the front and
top, 1 inch (25 mm) on the sides, and 1/2 inch (13
mm) from the back for air circulation AFTER the
compartment has been lined with metal and sound
insulation (Figure 6.4).
NOTE:
Refer to “Figure 5.2 – Major Features and
Dimensions” on Page 21.

6.2.2 COMPARTMENT CONSTRUCTION
• The generator compartment should be either con-
structed of, or lined with, 26-gauge galvanized
steel.
NOTE:
Aluminum is NOT an acceptable alternative
to galvanized steel due to aluminum’s low melting
point.
• If the compartment is lined with galvanized steel, it
may be constructed of any material. Generac rec-
ommends that the compartment be constructed of
1/2-inch thick plywood (not strandboard), with the
floor made of a double thickness of 1/2-inch ply-
wood with the grain of the wood at cross section
for added strength (Figure 6.5).
