PREPARATION TO SUPPLY THE ELECTRIC POWER

PREPARATION TO SUPPLY THE ELECTRIC POWER
1. Generator grounding
The end user, equipment owner or operator must
contact his local, state, county or municipal electric
code department to determine the approved generator
grounding method to be used in his application or
location.
Recommendations in the NEC (National Electrical
Code), NFPA (National Fire Protection Association),
AUSTRALIAN STANDARDS and OSHA (Occupational
Safety and Health Administration) regulations must be
followed to assure compliance and safe operation.
Always be sure to ground (earth) the generator
terminals to comply with the local, state, national or
OSHA requirements.
One possible connection method for construction site
use is as follows:
(1) Generator ground
terminal
(A) #6AWG
Flexible copper ground
connection
(B) Metal ground rod or building
cold water pipe system per
N.E.C. code
2. Recommended capacity of electrical
devices
APPLICATION RANGE
You can operate the GL-series generator in the
following range.
Typical
Apparatus
Light and
heaters
GL6000 5.5 kW
GL7000 6.5 kW
GL9000 8 kW
GL11000 10 kW
A Keep an inverter load below 50% of the generator
capacity.
A Make sure that total active mercury lamp load is
below 30% or so of the generator capacity. Turn on
the mercury lamps one by one. Be careful not to turn
off the lamps and on again immediately. The
generator voltage may rise to extremely high levels
and the AVR may get damaged.
A Before turning on the lamps again, wait for 10
minutes or so until the lamps cool down enough.
A The data shown above is only a guideline to
approximate load capacities and may vary from
generator model to generator model, with different
types of loads at rated outputs. These values may be
different from actual applications because of the
input characteristics peculiar to each load.
