GPS 8500 / GPS 9700 2.2 Operation Installation Place the generator in an area where it will not be exposed to rain, snow, or direct sunlight. Make sure it is positioned on firm, level ground, so it will not slide or shift. Position the engine exhaust away from areas where people may be present. The surrounding area must be free from water and moisture. All components must be protected from excessive moisture. DANGER DANGER Using a generator indoors CAN KILL YOU IN MINUTES.
Operation 2.3 GPS 8500 / GPS 9700 Generator Derating All generators are subject to derating for altitude and temperature. Internal combustion engines, unless modified, run less efficiently at higher altitudes due to the reduction of air pressure. This translates into a lack of power and thus reduction in generator output. Temperature affects both engine and generator performance. As temperature increases, an engine will run less efficiently and more resistance will be found in electrical components.
GPS 8500 / GPS 9700 2.4 Operation Grounding the Generator A ground connection (a) is located on the generator frame. For proper operating safety, this ground terminal must be connected to a good ground source. This ground connection must comply with National Electrical Code standards, and state and local regulations.
Operation 2.5 GPS 8500 / GPS 9700 Use of Extension Cords WARNING Current When a long extension cord is used to connect an appliance or tool to the generator, a voltage loss occurs—the longer the cord, the greater the voltage loss. This results in less voltage being supplied to the appliance or tool and increases the amount of current draw or reduces performance. A heavier cord with a larger wire size will reduce the voltage loss.
