  • Page 17: Operation

    GP 2500A Operation Operation Determining Power Requirements This generator is designed to operate single-phase, 60 Hz appliances running at 120 VAC. Check the nameplate or label provided on tools and appliances to make sure their power requirements match the power output of the generator.
  • Page 18: Installation

    Operation GP 2500A 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.
  • Page 19: Generator Derating

    GP 2500A Operation 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.
  • Page 20: Grounding The Generator

    Operation GP 2500A 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.
  • Page 21: Use Of Extension Cords

    GP 2500A Operation Use of Extension Cords 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.
