Fig. 3-1 Example of a type plate
3.2.1 A device description and intended use
Your power generator generates electrical power for supplying electrical con-
sumables, e.g. those used on assembly and construction sites.
The unit consists of an AC generator and a diesel drive engine that is firmly bolt-
ed onto it and an electric starter is used to start it. This unit is mounted elastically
inside a closed, sound-insulated housing, and vibration dampers are used to en-
sure low vibration.

10
Product identification
The unit generates AC (three-phase) current with a nominal voltage of 400V at
50Hz. More detailed technical data can be found in Chapter 13 . An integrated
voltage regulator ensures that the stability of the generated voltage is within the
nominal rotational speed range.
The generator is only to be used outdoors within the indicated voltage, output,
and nominal rpm ranges (see nameplate, Fig. 3-1 ).
The installation site must be chosen in so that air can flow around the generator
unhindered on all sides and, in particular, that the discharging of its exhaust can
be ensured. This is especially relevant as you must ensure that the sides with the
air inlet and the exhaust outlet are unobstructed.
The power generator is connected via CEE 400V sockets with a load capacity of
16A or 32A and 230V / 16A Schuko sockets.
Fuel is supplied from a 35 litre own tank, which can optionally be refilled using an
electric fuel pump or an external refuelling device.
The generator is not to be connected up to other power distribution systems (e.g.
public power supply) or to other power generating systems (e.g. other genera-
tors).
The generator is not to be used in explosion-prone environments.
The generator is not to be used in environments where there is a risk of fire.
The generator must be operated according to the specifications in the technical
documentation.
Any inappropriate use or any activities involving the generator that are not de-
scribed in this manual is prohibited misuse and they are outside the manufactur-
er’s legally defined liability limits.
3.2.2 Foreseeable misuse
Apart from the description of appropriate use, the lawmaker also requires
concrete references to the results of “reasonably foreseeable misuse“. In
a case of incorrect use or inappropriate handling of the generator the man-
ufacturer's EU Declaration of Conformity, and automatically thereby also
the operating licence, are nullified. For products with a manufacturer’s war-
ranty the manufacturer will reject any claims made under warranty for dam-
ages which were caused by misuse and its direct as well as indirect
consequences.
In particular unauthorised misapplications include:
• operation of the generator takes place without valid checks for
– electrical safety
– checking that the stipulated servicing and maintenance work has been
done
• operation of the generator taking place without the protective equipment in-
stalled by the manufacturer
• constructional or electrical modifications were made to the generator
• software was modified or changes were made to the generator's factory set-
tings
• use of the generator by inadequately instructed operating personnel
Furthermore at all costs avoid the following Misuses:
• Never refuel the generator’s own tank when the engine is running. The vibra-
tions and strong exhaust streams during operation can lead to fuel spillage.
This leads to an increased risk of explosion and fire and therefore danger to
operating personnel, the environment and the device.

11
Product identification
• Never refuel the generator’s own tank when it is hot. Overflowing fuel and ex-
haust fuel vapours can ignite on hot parts of the device.
• Never open the generator’s tank cover whilst it is running or if it is hot. Over-
flowing hot fuel and escaping fuel vapours can ignite on the device’s hot
parts.
• The generator is never to be connected up to another energy distribution sys-
tem (e.g. public power supply) or to other power generating systems (e.g.
other generators, solar plants, etc.). To start with this is usually not permitted
by . In both cases this will inevitably lead to severe damage and possibly also
severe injury.
• Never place the generator in explosion-prone environments. The individual
components of the generator are not designed to be EX-protected.
• Never operate the generator in rooms, narrow pits or vehicles. The combus-
tion exhaust gases contain poisonous substances including the odourless
but deadly gas carbon monoxide (CO) which, when breathed in, can accu-
mulate in cases of poor air circulation to reach deadly concentrations. Also a
lack of fresh air circulation leads to overheating and possible damage to the
generator right through to destruction.
• For the same reasons of risk, never divert exhaust gases for the purposes of
heating rooms or vehicles.
• Never clean the generator with the aid of a high pressure cleaner or a strong
jet of water.
• Never allow water to find its way inside the generator. Never pour water over
the generator and never clean it using a water hose or a high pressure clean-
er.
• Never operate the generator in any area where it could be flooded by high
water or any other events. The device's protection class (see Chapter 13 )
allows operation with spray water, however not in the case of floods.

Concrete warning notices can also be found regarding basic safety instructions
further on in this operating manual. These are always placed in an explanatory
text immediately before the description of work steps which can be dangerous if
the warning notice is not observed. Read the following sections for correct and
rapid understanding of these safety and warning notices. They describe their
systematic structure as well as the meaning of markings and symbols.
4.1 Safety symbols
The safety symbol indicates graphically that a source of danger exists. We
use the internationally valid safety symbols from ISO 7010 for rapid and
unique classification of the respective dangerous situation. In the follow-
ing there is a description of the warning symbols used in this operating
manual with an explanation about the respective dangerous situations.
Warning of a general hazard
This warning symbol indicates activities where several causes can lead to risks.
The concrete danger must be respectively more clearly specified by further no-
tices.
Warning of a dangerous electrical voltage
This warning symbol is indicates activities where the danger of electric shock ex-
ists, possibly with lethal consequences.
Warning of potentially explosive materials
This warning symbol indicates activities where the danger of an explosion exists,
possibly with lethal consequences.

4.2 General safety instructions
ENDRESS Generators are designed to operate electrical equipment with
appropriate power output requirements. Other uses can lead to severe in-
jury to operating personnel and people nearby. There is also increased risk
of damage to the generator and further property damage.
DANGER!
Mortal danger due to an electric shock if live parts are touched.
► Never operate the device if it is in a damaged condition.
► Never operate the electrical consumers and connecting cable (power con-
suming equipment) in a damaged condition.
► Never feed directly into existing networks that are already connected to a
power source (e.g. power supplier, solar plant, etc.).
► Never operate the device with wet hands.
Most injuries and equipment damage can be avoided if all instructions given in
this manual and all instructions attached to the device are followed.
The Generators must not be modified in any way, not even temporarily. This pose
a death hazard to operating and deployed personnel and damage to the gener-
ator and the consumers being used.
Operating company and Operating personnel are to use the Generators only ac-
cording to regulations contained in the entire technical documentation (hereinaf-
ter referred to as appropriate use).
Every instance of inappropriate use and all activities on the Generators that are
not described in this manual are prohibited misuse beyond the legally defined
limits of the manufacturer’s liability. In return all claims for damages and warranty
claims against ENDRESS-Elektrogerätebau GmbH that are associated with mis-
use are null and void.
4.3 Residual risks
As a manufacturer of EU-compliant machines, ENDRESS make great ef-
forts to create designs which already eliminate possible risk potentials at
the design stage. If this is not possible without significantly impairing the
functions of a device, we implement suitable protective measures protect
the user from injury.
If there are still some residual risks associated with working with the de-
vice, we clearly advise the user about these sources of danger, possible
consequences as well as measures to avoid such dangers.
The residual dangers were analyzed and Residual dangers identified during the
development and design of your Generators by means of a danger analysis ac-
cording to DIN EN 60204, DIN EN ISO 12100 and DIN EN ISO 8528-13.
References to general sources of danger can be found in chapters 4 and 5 .
From Chapter 6 one can find concrete warning notices placed before every ac-
tion step which represents a residual risk.
The exact structure and contents of warning notices are defined in the
ISO 3864 series of standards and follow an established identification mark-
ing required to immediately be able to estimate the degree of the respective
danger. Exactly impress upon yourself the identification marking of the

four different danger levels in order to be able to reliably assess the dan-
gers associated with the individual operating states and action steps when
reading the operating manual.
DANGER!
DANGER describes a danger which represents a high level of risk,which
can lead to death or severe injuries,when not avoided.
► The individual points provide instructions and
► notices as aids to avoid the danger
► or to reduce the risk to an acceptable level.
WARNING!
WARNING describes a danger which represents a medium level of
risk,which can lead to death or severe injuries,when not avoided.
► The individual points provide instructions and
► notices as aids to avoid the danger
► or to reduce the risk to an acceptable level.
CAUTION!
CAUTION describes a danger which represents a low level of risk,which
can lead to minor or medium level injurieswhen not avoided.
► The individual points provide instructions and
► notices as aids to avoid the danger
► or to reduce the risk to an acceptable level.
NOTICE!
ATTENTION! describes a situation or action that might result in damage to
equipment and/or malfunctions if it is not prevented.
► The individual points provide instructions and notices
► as an aid to avoid or prevent damage to equipment.
DANGER!
Mortal danger due to an electric shock if live parts are touched.
► Never operate the device if it is in a damaged condition.
► Never operate the electrical consumers and connecting cable (power con-
suming equipment) in a damaged condition.
