Installation and Setting-up Instructions

2-5. Installation and Setting-up Instructions. a . General. The engine generator set should be installed on a level site, clear of obstacles, and with ample ventilation. The site must be within 25 feet of any paralleled generator set, 25 feet of any auxi- liary fuel supply and 500 feet of any remote control area. b . Outdoor Installation. When preparing for a permanent installation, be sure the base is solid enough to support the weight of the unit. See figure 2-1 for dimensions of the base. Select a location where there will be sufficient space on all sides for servicing and operation of the engine generator set. When preparing a temporary installation, move the engine generator set as close to the worksite as practical. Use suitable planks, logs, or other material for a base in an area where the ground is soft . c. Indoor Installation. Keep the area well venti- lated at all times, so that the engine generator set will receive a maximum supply of air. If a free supply of fresh air is not available, provide duct work, with an opening at least as large as the radiator, to the outside of the installation. If louvers are used at the air entrance, increase the duct work size by 25 to 50 percent. Loosen the screw and nut which secure the weather cap to the exhaust outlet and re - move the weather cap. Install a gas-tight metal pipe exhaust from the exhaust outlet to the outside of the installation. The termination of the exhaust pipe shall be such that hot gases or sparks will be dis - charged harmlessly and will not be directed against combustible material or into an area containing flammable gases or vapors. Use as few bends in the pipe and as short a pipe as possible. The ex- haust pipe should include a low point with suitable means for draining of condensate. Provide metal shields, 12 inches larger in diameter than the ex- haust pipe where the line passes through flammable walls. Wrap the exhaust pipe with asbestos if there is any danger of anyone touching it. Refer to figure 2-1 for dimensions, air flow requirements and floor loading requirements. WARNING Do not operate the engine generator set in an enclosed area unless the exhaust gases are piped to the outside. Inhalation of exhaust fumes will result in serious illness or death. d. Leveling, The engine generator set is a portable unit and is designed to operate satisfactorily up to 15° out-of-level. Set up the unit as level as possible and keep it as level as possible during operation. e. Grounding. The engine generator set must be grounded prior to operation. The ground can be, in order of preference, (1) an underground metallic water piping system, (2) a driven metal rod or (3) a buried metal plate (fig. 2-2). If the effectively grounded portion of the buried metallic water pipe is less than 10 feet due to insulated sections or joints, this preferred grounding method must be supplemented by an additional driven metal rod ground or a buried metal plate ground. A driven metal ground rod must have a minimum diameter of 5/8 inch if solid or 3/4 inch if pipe, and driven to a minimum depth of 8 feet. A buried metal ground plate must have a minimum area of 9 square feet, minimum thickness of 1/4 inch, and be buried at a minimum depth of 4 feet. The ground lead must be at least No. 6 AWG (American Wire Gauge) copper wire. Ground rods are available as optional equipment. The procedures for making a ground connection are shown in figure 2-2. f. Generator Load Connections. Instructions for making the required generator load connections are designated in figure 2-3. 2-6. Equipment Conversion. a. Conversion instructions for equipment opera- tion at 120/208 Vac or 240/416 Vac are given in figure 2-4. b . Conversion instructions for equipment opera- tion of 50 or 60 Hz are given in figure 2-6. c. Conversion instructions for remote operation by removal and relocation of the control cubicle are given in paragraph 2-23. Figure 2-1A. Noise level warning. Change 2 2-3
