1. 1 This specfication covers the water-colled, diesel engine-driven ACgenerator model DCA-45SPI (hereafter referred to as generating set).

1.2 This generating set shall be designed, manufactured and tested in accordance with the latest standards of of JIS, JEC and JEM. JIS: Japanese Industrial Standard JEC: Standard of the Japanese Electrtechnical Committe JEM: The Standard of the Japan Electrical Manufacture’s Associationother matters which are not specifically mentioned in the above standards shall be subject to Denyo Co.,Ltd.’s production regulations.

2. GENERAL

2.1 Materials and WorkmanshipThe materials used in the manufacture ofthis equipment shall be of thehigh quality, an shall be free from defects and imperfections.All materials and apparatus not manufactured by Denyo Co., Ltd. shall bethe products of wel;-known manufacturers. The workmanship shall be of thehigh grade and in accordance with the most efficient, up-to-dateprocedures.

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 oradditional equipment which may result in an increase or decrease ofequipment’s cost, such modifications shall be made in writing and agreed toby both parties prior to production and shall constitute an amendmentto these specifications.

2. 3 Tests and InspectionsRout tests and ispections shall be final in our factory.if any tests and ispections beyond the scope of Denyo’sstandardcommercial procedures are required by the purchser, charges for suchinspections or testsshall be added to our estimate. Conditions of any suchtests and inspections shall be mutually agreed upon between both parties.

2.4 Ambient Conditions This generating set should meet the following conditions: (1) Ambient temperature : -5 ْC or higher, 35 ْC or lower (2) Altitude : up to 500m above sea level (3) Relative humidity : 85% or lower (4) Place of installation : indoor and outdoor

3 . S T R U C T U R E

The generating set prossesses a solid structure, and is comprised of a water-cooleddiesel 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 couplingof the engine and generator is ensured by tight connection ofthe housing exterior. The rotating section of the generator is directly coupledto the flywheel of the engine with a flexible coupling plates made of laminatedthin steel. The generator is of single bearing construction.The standard generator is of the brushless thpe.Aheavy gauge steel bonnet and side door completely cover the engine,generator and accessories, protecting the unit from effects of weathe orpossible handling damages at the construction site. A lifting hook is attached to the common base, and it extends to the balance point throug the bonnet top.
