3.2 Description and purpose of the machine

This machine is a portable power source. The portable generator from
Wacker Neuson consists of a steel pipe frame, which includes a fuel tank, a
gasoline engine, a control panel and an electrical alternator. The control panel
contains controls and bushings. When the engine is running, the generator con­verts the mechanical energy into electrical energy. The operator connects elec­tronic loads to the mains sockets.

This machine is used for the electric power supply of connected electronic loads.
See the product specifications for output voltage and frequency of th e generator
as well as the maximum power limitation of this generator.

This machine was designed and built exclusively for the aforementioned purpo­se. Use of the machine for any other purpose could permanently damage the
machine or cause serious injury to the operator or other persons in the vicinity.
Machine damage due to misuse is not covered by the warranty.

The following practices are considered misuse:

 Connection to an electronic load whose voltage and frequency are not com-

patible with the generator output

 Overloading the generator with a load that takes too much power durin g con-

tinuous operation or when starting

 Operating the generator in a manner that is inconsistent with the national,

statewide and local standards and regulations

 Use of the machine as a ladder, support or working surface
 Operation of the machine to carry or transport people or equipment
 Operation of the machine outside of the plant specifications
 Operation of the machine contrary to warning notices attached to the machi-

ne and contained in the operator's manual.

This machine was designed and built according to the latest global safety stan­dards. In order to eliminate dangers as much as possible, it was technically de­signed with great care and contains protective side plates and warning labels for
an increased safety of the operator. Additional risks may exist despite these pro­tective measures. These are designated as residual risks. Possible residual risks
with this machine:

 Heat, noise, exhaust and carbon monoxide from the engine
 Risk of fire due to incorrect refueling procedure
 Gasoline or gasoline vapors
 Electric shock and arc discharge
 Injury due to incorrect hoisting technology

3.3 Operational safety

GEFAHR
Carbon monoxide.

The application of a generator in buildings can

LEAD TO DEATH WITHIN MINUTES. The exhaust fumes from the generator
contain carbon monoxide (CO). This is an invisible odorless poison. If the
exhaust fumes of the generator can be smelled, CO is being inhaled. Even if no
exhaust fumes can be smelled, CO could still be being inhaled.

 NEVER use the generator in buildings, garages, crawl spaces or other parti-

ally enclosed areas. Carbon monoxide can build up to deadly levels in these
areas. A fan or open window does NOT provide sufficient fresh air.

 ONLY use generators out doors and far away from windows, doors and aera-

tion. These openings can draw in generator exhaust fumes.

 CO can penetrate into a home, even if a generator is used properly. AL-

WAYS use a battery-powered or battery-backup CO alarm in the home.

 IMMEDIATELY get to fresh air if you feel unwell, dizzy or weak after using

the generator. Consult a physician. It could be carbon monoxide poisoning.

WARNUNG

Electric shock or risk of fire or explosion. Incorrect connection of the generator
to a building's mains supply can lead to current being lead from the generator
back into the power supply system. This can cause electric shock, serious injury
or death of the worker in the public utility company!

4. Now attach components that are not yet fastened.

5. Fill fluids as needed, including fuel, engine oil and battery acid.

6. Bring the machine to its site of operation.

Use of gasoline / ethanol mixtures

This portable generator may not be used with gasoline / ethanol mixtures with
more than 15 % ethanol content.

DANGER
Carbon monoxide.

The application of a generator in buildings can

LEAD TO DEATH WITHIN MINUTES. The exhaust fumes from the generator
contain carbon monoxide (CO). This is an invisible odorless poison. If the ex­haust fumes of the generator can be smelled, CO is being inhaled. Even if no
exhaust fumes can be smelled, CO could still be being inhaled.

 NEVER use the generator in buildings, garages, crawl spaces or other par-

tially enclosed areas. Carbon monoxide can build up to deadly levels in
these areas. A fan or open window does NOT provide sufficient fresh air.

 ONLY use generators out doors and far away from windows, doors and aera-

tion. These openings can draw in generator exhaust fumes.

 CO can penetrate into a home, even if a generator is used properly. AL-

WAYS use a battery-powered or battery-backup CO alarm in the home.

 IMMEDIATELY get to fresh air if you feel unwell, dizzy or weak after using

the generator. Consult a physician. It could be carbon monoxide poisoning.

7 Operation

100_0402_op_0003.fm 23

7.2 Power requirements

The Wacker Neuson generator GV 7000A is designed for the operation of single­phase 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 triple­phase 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 yo u 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 start­up 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

7 Operation

24

100_0402_op_0003.fm

7.3 Installation

Set up the generator so it is protected from rain, snow or o ther forms of moisture.
The ground must be solid and level in order to prevent slipping or displacement.
Do not direct the engine exhaust to an area with people.

Both the work area as well as the components must be protected from all forms
of moisture.

7.4 Current depreciation

Generators run differently due to altitude and temperature differences.
Unmodified internal combustion engines have reduced performance at high
altitudes due to the lower air pressure. This means less performance and
therefore a reduced power exploitation. As soon as temperatures increase, an
engine runs less economically and electrical components have more resistance.

For every 500 meters above high altitudes of 1000 meters above sea level, the
performance of the generator is reduced by 3%. For outside temperatures above
40 degrees Celsius, the generator performance is reduced by 3% for every
additional 5 degrees. The tables shown help with the high altitude and outside
temperature performance devaluation. In order to determine the true generator
performance, it may be necessary to consider both the high altitude and
temperature devaluation factors.

7.5 Ground

For generator sets that are to supply a facility in a TT network, or if residual
current protection is required in the TT network, or if this equipment must be used
for additional protection due to conditions or regulations, only 30 mA residual
current protective switches may be used as protective devices. The 30 mA
residual current protective switch must be installed ON the generator set itself,
but at least on the nearest possible position in relation to the generator set. Only
with this type of installation is it allowed and necessary to establish the ground
connection of the generator framework via the point provided on the frame (see
ground symbol 5019).

7.6 Heavy duty operation

Do not operate this generator for longer than 20-30 minutes under maximum
electrical load rating. For continuous operation, do not exceed the continuous
(prime) power output of the generator. See technical data of the generator in this
operator's manual.

CAUTION

The mid-point (neutral) conductor of this equipment is not grounded.

Do not
drive the PE rod into the ground under normal operating conditions.
Refer to the local regulations if the equipment is intended to power a
building or similar system.

7 Operation

100_0402_op_0003.fm 27

7.7 Use of extension cables

A loss of power takes place when connecting electrical equipment or a tool to the
generator with an extension cable — the longer the cable, the greater the loss of
power. This means that less voltage is conveyed to the electrical equipment and
the power consumption is increased or the performance is reduced. A larger
extension cable diameter reduces the loss of voltage.

NOTE: Operation of electrical equipment under low voltage may lead to
overheating.

The table serves as a guideline for selecting the correct cable size.
Only strong, rubber-covered cables can be used that correspond to regulation

IEC 245-4.

Never exceed the cable's rated power.
Contact the cable manufacturer if you have questions about using the cable.
Select the cable size from the table Minimum cros s-se cti on o f extension cables

or calculate the minimum cross-section using the graph Minimum cross-section
of extension cables. The X-axis of the graph stands for the values A x m (ampere
x meter). The Y-axis stands for the cross-section in mm². Multiply the steady
state (operating) current for the load in ampere (A) with the desired length of the
extension cable in meters (m). Now look for your result on the X-axis. Go along
the graph until you have found the point for your field of application. Now read
the recommended minimum cable length on the Y-axis.

Example
For example, if there is a triple-phase application with 400 V of steady state

(operating) current available for the load at 15 A and the desired extension cable
length is 100 m, then:

15 A x 100 m = 1500 A x m.
1500 A x m = 2.5 mm².

WARNING

Damaged cables may cause electric shock, which can lead to serious injury or
death.

NEVER use worn, bare or frayed cables. Replace damaged ca-

bles immediately.

10 Disposal

10.1 Disposal of waste electrical and electronic equipment

Professional disposal of this machine avoids negative effects on human health
and the environment, helps with the targeted treatment of pollutants and makes
it possible to recycle valuable raw materials.

For customers in EU countries

This machine is subject to the European directive for old electrical and electronic
equipment (Waste Electrical and Electronic Equipment (WEEE)), as well as the
corresponding national laws. The WEEE directive provides the framework for an
EU-wide treatment of old electrical equipment.

The machine is marked with the following symbol of a crossed-out
garbage bin. This means that you do not dispose of the battery in
normal household waste but that it must be disposed of in a sepa­rate, environmentally friendly collection facility.

This unit is provided as a professional electrical tool exclusively for
commercial use (a so-called B2B device according to the WEEE directive). Un­like equipment mostly used in private households (so-called B2C devices), this
machine may therefore not be disposed of in some EU countries, such as in Ger­many, at the collection points of public waste management organizations (e.g.
municipal collection stations). If there are any doubts, information regarding the
different methods of disposal for B2B electronic devices for each country can be
obtained from the sales location, so that the disposal takes place in accordance
with the valid statutory provisions. There are also some notes to follow in the sa­les contract or in the general Terms and Conditions of the sales location.

For customers in other countries

It is recommended that you do not dispose of the machine in normal household
waste but rather in a separate, environmentally friendly collection facility. Natio­nal laws also may, under certain circumstances, prescribe the separate disposal
of electrical and electronic products. Correct disposal of this machine in accor­dance with current national guidelines must be assured.
