7.2 Power requirements
The Wacker Neuson generator GV 7000A is designed for the operation of single-
phase 50 Hz electronic devices for 230 VAC. Generator
GV 7003A is designed
for the operation of single-phase 50 Hz electronic devices for 230 VAC and/or
triple-phase 50 Hz electronic devices for 400 VAC. The single-phase or triple-
phase sides can be used at the same time.
NOTE: Do not exceed the performance limit of the generator, as this may lead
to damage of the generator or the tools. See Technical Data.
Check the nameplates or labels of the tools and electronic equipment to be
connected to ensure that the current values conform with those of the generator.
Always inquire with the manufacturer if equipment is lacking the wattage.
Some electrical equipment requires a great amount of power to start than to
operate. The generator must be able to convey this power. Different equipment
designs actually require more current than specified on the nameplate.
The "general power requirements when starting" information only applies as a
general guideline to assist you in determining the power requirements. The
nearest Wacker Neuson dealer, tool manufacturer or dealer can help you if you
have questions.
NOTE: Do not exceed the specified current intensity limit at any plug receptacle.
NOTE: If a tool or electrical equipment should not reach the full RPM a few
seconds after starting, switch it off immediately in order to prevent damage.
General power requirements for starting

White light bulbs and electronic goods, such as irons and hot plates, use a
resistor heating element and require the same amount of power during start-
up that is listed on the nameplate.

When starting, neon and mercury lamps require 1.2-2 times the specified
wattage.

Many electric motors and power tools use a large amount of power when
starting. The electrical supply required during start-up depends on the type
of motor and the intended application.

When starting, most power tools require 1.2-3 times the specified wattage.

Connection units, such as submersible pumps and air compressors, require
a large amount of power when starting, even up to 3-5 times the specified
wattage.
If the wattage of a tool or electrical equipment is not specified, this can be
calculated by multiplying the voltage requirements with the amperage
requirements.
Single-phase: VOLTS x AMPS = WATTS
Three-phase: VOLTS x AMPS x 1.732 x 0.8 = WATTS
