CAUTION:
Earth Leakage Breaker (180 Cycle)
The 180 Hz leakage breaker (Figure 4) is an earth leakage
breaker, so please use it after carefully reading the following:
The earth leakage breaker's earth leakage detection
sensitivity is 30 mA, and the actuation time is 0.1 sec.
GDP-5000H — LOAD APPLICATION
z
Always use a vibrator with short circuit
protection.
z
Always use rubber boots and gloves
when operating the vibrator.
z
Use adequate size connecting cable
for extension.
z
Maintain electrical cords in good
condition and frequently replace the
entire cable of the vibrator with a new
one.
WARNING:
Before connecting this generator to any
building’s electrical system, a licensed
electrician must install an isolation
(transfer) switch.
Serious injury or death may result without
this transfer switch.
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.
Test Operation
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
.

NOTE
Before operating generator press
earth leakage test button.
NOTE
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.
