GDP-5000H — PRE-SETUP

General Inspection Prior to Operation

This generator has been thoroughly inspected prior to shipment from the factory. However, be sure to check for damaged parts or components, or loose nuts and bolts, which could have occurred in transit.

Ground

The nut and ground terminal on the generator should always be used to connect the generator to a suitable ground. The ground path should be of #8 size wire.

Connect the terminal of the ground wire between the lock washer and the nut and tighten the nut fully. Connect their end of the wire to a suitable ground.

Ground the Generator

Ground the generator from its ground connector so that the resistance to ground is 500 ohms or less.

Ground the Tool

Ground the tool (load) in the same manner as the generator.

Circuit Breaker

To protect the generator from an overload, circuit breakers are provided for both 60 and 180 phases on the control box. Make sure to switch the circuit breakers to the "OFF" position prior to starting the engine.

Extension Cable

When electric power is to be provided to various tools or loads at some distance from the generator, extension cords are normally used. Cables should be sized to allow for distance in length and amperage so that the voltage drop between the generator and point of use (load) is held to a minimum. Use the cable selection chart (Tables 2 and 3) as a guide for selecting proper cable size.
