Multiquip GDP-5H manual Three Phase Load 180 Hz, How to Use, Ground the Generator, Ground the Tool

Three Phase Load — 180 Hz

180 Hz, three phase, 230V, motor-in-head vibrators can be operated with this generator. When operating more than one concrete vibrator, the ON/OFF switch of each concrete vibrators shall be turned on one at a time.

If they are switched on simultaneously, the circuit breaker may trip or the engine may be overloaded.

The vibrators can be operated simultaneously if the total power consumption does not exceed the rated output of the generator (5.0 KVA).

How to Use

Always conduct the following in order that the earth leakage breaker will operate safely. Also, if the leakage breaker should for some reason actuate, first stop the generator and then repair or eliminate the source of the earth leakage before resetting the leakage breaker.When setting up the generator perform the following:

Ground the Generator

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

Ground the Tool

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

NOTE

Test Operation

Simply because the generator is equipped with a earth leakage breaker does not mean that grounding of the load can be neglected, please be sure to properly ground load equipment.

180 Hz application (3-phase vibrators). Before operating the generator test this breaker to make sure that is functioning correctly.

For safety’s sake, the operation of the earth leakage breaker should be tested periodically according to the following procedure:

1.Start the engine and set it to high speed.

2.Turn the leakage breaker ON.

3.During normal operation, press the earth leakage indicator test button on the front of the generator and observe that indicator button pops out and the leakage breaker trips.

4.Push the indicator button back in when resetting.
