These bolts must pass through (a) the generator mounting base, (b) the compartment floor (if a compartment is used) and (c) the supporting 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.

Close windows, doors and other openings in the vehicle that, if open, might permit exhaust gases to enter the vehicle. —A ESE13 A— A The generator engine gives off DEADLY carbon monoxide gas through its exhaust system. This dangerous gas, if breathed in sufficient concentrations, can cause unconsciousness or even death. Never operate the generator set with the vehicle inside any garage or other enclosed area. DO NOT OPERATE THE GENERATOR IF THE EXHAUST SYSTEM IS LEAKING OR HAS BEEN DAMAGED. SY

. 2.2.3 ACOUSTICS For additional noise abatement, the installer may wish to consider the following: • Using special sound-insulating materials. • Construction of a special noise abatement compartment. NOTE: Any method used to reduce noise must not adversely affect the flow of cooling and ventilating air into, or out of, the compartment. In addition to the effective use of sound insulating materials, construction of a special noise abatement compartment might be considered to reduce noise levels.

The NEMA 1 enclosure is intended for indoor use only. The NEMA 3R enclosure is weather proof and can be used indoors or outdoors. Follow these rules: • Install the transfer switch on a firm, sturdy supporting structure. • To prevent switch distortion, level the switch if necessary. This can be done by placing washers between the switch enclosure and the mounting surface. • Never install the switch where water or any corrosive substance might drip onto the enclosure. • Protect the switch at all t
