GP/GPS 6600A Operation 25
Operation 5.7 GP/GPS 6600A 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.
GP/GPS 6600A 5.8 Operation Grounding the Generator See Graphic: wc_gr000544 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. 5.9 Operating Heavy Loads Limit operations requiring the maximum rated output of 6600 W to 20– 30 minutes.
Operation GP/GPS 6600A 5.10 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.
