Generator set location is critical for safety and performance. Follow the guidelines

below:

• The installation must comply with all applicable codes and standards (NFPA,

NEC, IBC, etc.).

• This manual only covers outdoor installations with Cummins factory installed

enclosures. This product must never be installed indoors.

• Consider access to utilities (electric meters, transfer switch, fuel supply line and

fuel tank, etc.).

• Call the local utilities to mark the locations of buried utility services (gas,

electric, telephone, etc.) before digging.

• Verify the locations of any other buried components (gas, electric telephone,

etc.) with the homeowner before digging.

• Consideration should be given to the location of sprinkler heads for irrigation

systems. The generator set should not be located where it is subjected to

substantial wetting (especially on the inlet air side) when the irrigation system is

in operation.

• Always install this generator set service regulator above the snow line.

Follow the clearance requirements below (refer to the Outline and System Drawings

appendix):

• All parts of the generator set enclosure must be at least 60 inches (1524 mm)

from any openings in walls of structures that may be occupied. Examples of

wall openings include but are not limited to: operable windows, doors, dryer

vents, fresh air intake for heaters, etc.

• The engine side and alternator side of the generator set must be located as

follows:

◦ One side (either engine or alternator) must be located not less than 18

inches (458 mm) from any structures having combustible walls. This space

must be free of any obstructions for service access.

◦ The opposite side must be located not less than 60 inches (1524 mm) from

any structures having combustible walls. A minimum of 18 inches (458

mm) of unobstructed space is required for service access.

• The intake (cooling air inlet) side of the generator set must be located not less

than 30 inches (762 mm) from any structures having combustible walls. This

space must be free of obstructions to air flow and service access.

• The generator set must be located such that exhaust gases are not able to

accumulate in an occupied area. The air discharge side must always be

unobstructed and spaced a minimum of 60 inches (1524 mm) from any

structures having combustible walls. A minimum of 36 inches (915 mm) must

be free of any combustible items, and unobstructed for service access.

• The generator set must have enough room for installation, service, and

maintenance.
