7 Operation
7.2
Use and input current
This generator is intended for the operation of single-phase 50 Hz electrical
equipment for 230 V.
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 more power to start than to operate. The
generator must be able to provide this power. Some equipment actually requires
more current than specified on the nameplate.
The "general input current when starting" information only applies as a general
guideline to assist you in determining the input current. In the event of questions,
the nearest Wacker Neuson service station will be able to assist you.
NOTE: Do not exceed the specified current 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
22
100_0402_op_0002.fm
7 Operation
7.3
Performance loss with high altitude application
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.

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 input current 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.
WARNUNG
Damaged cables may cause electric shock, which can lead to serious injury or
death. NEVER use worn, bare or frayed cables. Replace damaged
cables immediately.
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 cross-section of
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.

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.
