Series QP55-C Recreational Vehicle Generator
2.1 LOCATION AND SUPPORT
• 2.1.1 GENERATOR LOCATION_____________________
The most desirable location for the generator set is
between the vehicle's main frame members.
However, this is seldom possible. Most units must
be installed on the side of the vehicle and are diffi­
cult to reinforce.
Many recreational vehicles have been factory
equipped with an area for the generator set. Some
vehicles may even have a generator compartment
provided by the vehicle manufacturer.
Plan the generator location based on the following:
• The generator set must be installed on a frame­
work that is part of the recreational vehicle, as
outlined in Section 2.1.2.
• The location must provide an access opening that
is large enough to permit generator removal
(unless the generator is to be removed from
underneath the supporting framework).
• The location must provide easy access to fre­
quently serviced components, such as filters, oil
drains, spark plugs and other common mainte­
nance parts.
• The location must provide sufficient room to
allow minimum clearances as outlined in Section
2.2. If sound insulation is to be used on the com­
partment walls and ceiling, the minimum recom­
mended applies to the space between the gener­
ator and such insulation.
• The location must provide adequate cooling and
ventilating airflow for the generator without a
great deal of work and expense.
• 2.1.2 GENERATOR SUPPORT
The generator must be securely attached to a metal
framework that has been made part of the vehicle
frame structure by bolting or welding. The metal
framework on which the generator will rest and
which will restrain the generator set should consist
of at least two horizontal beams. These beams
should consist of (a) 1-1 /2-inch square, 11-gauge
steel tubing OR (b) 1-1/2-inch, 11-gauge angle
iron, A typical supporting frame with horizontal
support tubing, is shown in Figure 2.1.
The generator can be installed so that it sits on top
of the horizontal support tubing if the vehicle
design permits. Another method is to suspend the
generator below the horizontal support tubing by
means of suitable, structurally sound metal frame­
work. The following general rules apply:
• Vehicle construction MUST be capable of sup­
porting the weight of the generator.
Whether the generator is mounted above the hor­
izontal support tubing or suspended below the
tubing,
the supporting frame used must be
structurally sound.
If the generator cannot be bolted directly to
the supporting frame or support tubing, consid­
er
using additional tubing, angle brackets
or other supports to give the supporting frame
sufficient strength.

♦ 2.1.5 GENERATOR RESTRAINT
Use four 3/8"-16 hardened steel bolts (Grade 5) to
fasten the generator to the supporting frame or the
support tubing. These bolts must pass through (a)
the generator mounting base, (b) the compartment
floor (if a compartment is used) and (c) the support­
ing framework (Figure 2.3). All bolts must be long
enough so that when tight, at least three threads are
visible past the retaining lock nuts. Refer to Section
2.2 for the location of the generator mounting holes.
