About this manual
2.2 Using this operating manual
In order to increase the legibility, comprehensibility and transparency of
the document, certain information is highlighted or identified according a
uniform system. The following particularly belong in this category:
signs warning about dangers to life and limb
Safety and warning notices are necessary at all locations where there is potential
danger from the device which cannot be eliminated by design or operational
measures. We restricted ourselves to the permitted minimum in order to place
the required distinctive warning notices at the correct point in time without impair-
ing the legibility and comprehensibility of the operating manual. This is according
to the regulations contained in the international standard DIN ISO 3864 de-
scribes a fixed rule for all safety and warning notices, as shown in the following
example.
Examples:
DANGER!
Electrical voltage
Risk of suffering potentially deadly electrocution by touching live parts
► Only use undamaged connecting lines
► Avoid all damp / wetness when connecting consumers
► Never operate the power generator with an opened control panel
The standard mentioned classifies the safety risks according to different risk po-
tentials. To understand and avoid dangers to one’s health and even life, please
be sure to read the explanations given in Chapter 4.1 .
Safety symbols
These warning notices are usually used in a safety symbol which also emphasis-
es the type of danger; see next example. A list of the safety symbols used in this
operating manual can be found in Chapter 3.3 . The safety symbols never stand
alone.
Notices on avoidance of damage to the device
According to DIN ISO 3864, notices which warn against false operation and pos-
sible damage to the device or to the equipment used should be clearly distin-
guishable from previously named warning notices in as far there is no danger to
health. An example of such a notice can be seen here:
NOTICE!
Use of wrong or outdated fuel damages or destroys the engine.
► Only use released diesel fuel.
► Observe the shelf life of the fuel according to the supplier.
► Observe the Operating manual from the engine manufacturer

in exactly identifying your device. Refer to your generator's operating instructions
for further information about finding the type plate.
Fig. 3-1 Example of a type plate
3.2.1 A device description and intended use
Your power generator generates electrical energy for the "direct supply" mode as
part of a mains backup operation for supplying electricity to a mobile distribution
system. This enables mobile use of commercially available electrical devices
with single-phase 127V AC / 60Hz or three-phase 220V AC / 60Hz (depending
on the equipment being used).
Your power generator has been designed for manual or automatic operation (re-
mote start) with one or more electrical consumers. To protect against electric
shock (i.e. current flowing through your body), automatic switching off according

10
Product identification
to DIN VDE 0100-551: 2017-02 is used as the protective separation measure.
The protective conductor system from the attached consumers will take over the
earthing function. The terminal strip (Fig. 6-4 ) is used for connecting up a suit-
able earth (e.g. an earthing stake). Proper is needed and it must be implemented
by a qualified electrician.
Your generator consists of an AC generator that is driven by a combustion engine
that is bolted onto it. This unit is mounted elastically inside a closed and sound-
insulated housing and vibration dampers are used to ensure low vibrations. The
current is taken from the terminal strips through measures implemented by an
electrician.
The unit generates three-phase AC (three-phase current) with a nominal voltage
of 220V at 60Hz. More detailed technical data can be found in Chapter 12 . An
integrated voltage regulator ensures that the stability of the generated voltage is
within the nominal rotational speed range. The current is drawn off through the
connection terminal.
The generator is only to be used outdoors within the indicated voltage, output,
and nominal rpm ranges (see type plate).
The power generator must never be used for direct feeding into other power dis-
tribution systems (e.g. public power supply) or be used with other power gener-
ation systems (e.g. other power generators).
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.
Every inappropriate use or all activities on the generator which are not described
in these instructions is forbidden misuse outside the legally defined limits of lia-
bility of the manufacturer.
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 EC 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.
As not authorised Misuse is particularly the case when:
• operation of the generator takes place without valid checks for
– electrical safety
– checking that the prescribed servicing and maintenance work has been
done
• operation of the generator takes place without the protective equipment in-
stalled by the manufacturer
• constructional or electrical modifications of the generator were undertaken
• 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
outflowing fuel vapours can ignite on hot parts of the device.
• The generator is never to be connected up to other energy distribution sys-
tems (e.g. public power supply) or to other energy generation systems (e.g.
other generators, solar plant, etc.). To start with this is usually not permitted
by the energy supply company. In both cases this will inevitably lead to se-
vere damage and possibly also severe injury.
• Never place the generator in explosion-prone environments. The individual
components of the generator are not designed 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 Protection Class of the device (see Chapter
12 ) allows operation for spray water, however not in the case of floods.

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-
juries to operating personnel as well as persons nearby. There is also in-
creased risk of damaging the generator as well as further 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.
► 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.
The majority of injuries and damage to equipment can be avoided if all instruc-
tions given in this manual and all instructions attached to the device are followed.
The generator must not be modified in any way, also not temporarily. This can
lead to a mortal risk to operating and deployed personnel and damage to the gen-
erator as well as the consumers being used.
Operating company and Operating personnel may only use the generator ac-
cording to regulations contained in the whole technical documentation (hereinaf-
ter referred to as appropriate use).
Every instance of inappropriate use as well as all activities on the generator
which are not described in these instructions are forbidden misuse outside the
legally defined limits of liability of the manufacturer. In return all claims for dam-
ages and claims made under warranty to ENDRESS-Elektrogerätebau GmbH

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.
