1.2 This generating set shall be designed, manufactured and tested in accordance with the
latest standards of JIS, JEC and JEM.
JIS : Japanese Industrial Standard
JEC : Standard of The Japanese Electrotechnical Committee
JEM : The Standard Of The Japan Electrical Manufacturer's Association
Other matters which are not specifically mentioned in the above standards
shall be subject to Denyo Co., Ltd.'s production regulations.
2. GENERAL

well-known manufacturers. The workmanship shall be of the high grade and in
accordance with the most efficient, up-to-date procedures.
2.2 Change
Minor changes after the final design may be made by Denyo Co., Ltd. without prior notice
to the Purchaser. In case of major changes or additional equipment which may result in an
increase or decrease of equipment's cost, such modifications shall be made in writing and
agreed to by both parties prior to production and shall constitute an amendment to these
specifications.

3. STRUCTURE
The machine possesses a solid structure, and is comprised of a water - cooled diesel
engine and a generator, which are directly coupled on a common base.
A coupling housing is employed to connect the generator to the engine. Firm coupling of the
engine and generator is ensured by tight connection of the housing exterior. The rotating
section of the generator is directly coupled to the flywheel of the engine.
The generator is of single bearing construction.
The standard generator is of the brushless type.
A heavy gauge steel bonnet and side door completely cover the engine, generator and
accessories, protecting the unit from effects of weather or possible handling damages at the
construction site.
A lifting hook is attached to the common base, and it extends to the balance point through
the bonnet top.
