Section 2 - Introduction
2.1 About This Manual
This manual provides installation instructions for the
generator set models listed on the front cover. This
includes the following information:
Mounting Recommendations - for fastening
the generator set to the base and space require-
ments for normal operation and service.
Mechanical and Electrical Connections - cov-
ers most aspects of the generator set installa-
tion. Pre-start - checklist of items or procedures
needed to prepare generator set for operation.
Initial Startup - tests the complete system to
ensure proper installation, satisfactory perfor-
mance, and safe operation. Refer to Operator
Manual for troubleshooting information.
Installation Checklist - reference checks upon
completion of installation.
This manual DOES NOT provide application informa-
tion for selecting a generator set or designing the
complete installation. If it is necessary to design the
various integrated systems (fuel, exhaust, cooling,
etc.), additional information is required. Review stan-
dard installation practices. For engineering data spe-
cific to the generator set, refer to the Specification
and Data Sheets. For application information, refer to
Cummins Application Manual T-030, Liquid Cooled
Generator Sets.
2.2 Installation Overview
These installation recommendations apply to typical
installations with standard model generator sets.
Whenever possible, these recommendations also
cover factory designed options or modifications. How-
ever, because of the many variables in any installa-
tion, it is not possible to provide specific
recommendations for every situation. If there are any
questions not answered by this manual, contact your
nearest Cummins distributor for assistance.
2.3 Application and Installation
A power generation system must be carefully
planned and correctly installed for proper operation.
This involves two essential elements: application and
installation.
Application (as it applies to generator set installa-
tions) refers to the design of the complete power gen-
eration system that usually includes power
distribution equipment, transfer switches, ventilation
equipment, mounting pads, and cooling, exhaust, and
fuel systems. Each component must be correctly
designed so the complete system will function as
intended. Application and design is an engineering
function generally done by specifying engineers or
other trained specialists. Specifying engineers or
other trained specialists are responsible for the
design of the complete standby system and for
selecting the materials and products required.
Installation refers to the actual set-up and assembly
of the power generation system. The installers set up
and connect the various components of the system
as specified in the system design plan. The complex-
ity of the system normally requires the special skills of
qualified electricians, plumbers, sheet metal workers,
etc. to complete the various segments of the installa-
tion. This is necessary so all components are assem-
bled using standard methods and practices.
2.4 Safety Considerations
The generator set has been carefully designed to
provide safe and efficient service when properly
installed, maintained, and operated. However, the
overall safety and reliability of the complete system is
dependent on many factors outside the control of the
generator set manufacturer. To avoid possible safety
hazards, make all mechanical and electrical connec-
tions to the generator set exactly as specified in this
manual. All systems external to the generator (fuel,
exhaust, electrical, etc.) must comply with all applica-
ble codes. Make certain all required inspections and
tests have been completed and all code requirements
have been satisfied before certifying the installation is
complete and ready for service.
