SAFETY INFORMATION 1
When installing the generator, pay attention to the ca-
pacity of electrical appliances and their starting current,
which may be several times higher than the rated cur-
rent. The generator cannot run in overload conditions
when starting consumers with an inrush current higher
than the generator’s maximum output.
As exhaust gases contain poisonous carbon dioxide (CO2)
and carbon monoxide (CO) gases which are dangerous
for life, it is strictly forbidden to install the generator in
residential buildings, premises connected to residential
buildings by a common ventilation system, other rooms
from which exhaust gases may enter living premises.
ATTENTION – DANGER!
ATTENTION – DANGER!
WORKING AREAWORKING AREA
- Do not use generator in the rain, snow and high humidity conditions, do not touch the generator with wet
hands. It’s prohibited to leave it in direct sunlight in summer for a long time. It is recommended to store
and use the generator under a canopy or in a well ventilated area.
- Place the generator on a at, hard surface, away from ammable liquids/gases (at a minimum distance of
1 m). Install the generator at a distance of not less than 1 m from the front control panel and not less than
50 cm on each side, including the upper part of the generator. To reduce vibration during operation and to
avoid damage to the surface, where the generator is installed, it is equipped with dampers.
- Please don’t use the generator near ammable gases, liquids or dust. When using the generator exhaust
system gets very hot. This may cause re or explosion of these materials.
- Be sure to follow cleanliness and good lighting in the work area. Clutter and poor lighting may cause an
injury. uk.koenner-soehnen.com |1

- The generator produces electricity that may lead to an electric shock while neglecting compliance regu-
lations.
- Könner & Söhnen generators were initially designed as an IT system with basic protection by insulation
of hazardous live parts according to DIN VDE 0100-410. The generator housing is insulated from the cur-
rent-carrying L and N conductors. The generator must be grounded in all cases, except for an IT system with
an insulated neutral wire and bonding. A grounded IT system requires the use of an insulation monitoring
device. Further details regarding the use of the generator in IT and TN systems can be found on our website
or requested from our technical support.
- All connecting the generator to the network must be made by certied electrician in accordance with all
electrical rules and regulations.
- It is not allowed to supply current from the electrical network to the generator when the power supply is
restored.
- Do not allow moisture in the generator. The water inside the device increases the risk of an electric shock.
- In the high humidity level conditions generator exploit is prohibited. Keep the generator in a dry place
only.
- Avoid direct contact with grounded surfaces (pipes, radiators, etc.).
- Be careful when working with power cables. Immediately replace it in case of damage, as damaged wire
increases the risk of electric shock.
- Network connection should only be carried out by a qualied technician
- Connect the generator to the protective ground before operation.
- Do not connect or disconnect a generator to electricity consumers, which are placed in water on a wet or
damp soil.
- Do not touch parts of the generator under voltage.
- Connect the generator to those customers only which meet the electrical characteristics and the rated
power of the generator.
- Store all electrical equipment dry and clean. Wires with damaged or spoiled insulation should be re-
placed. You should also replace worn, damaged or rusty contacts.
The generator and power consumers form a closed system, with elements aecting each other. This system
is physically dierent from the public network since it is signicantly aected by factors such as unbalanced
phase load and non-linear current consumption by power consumers that can cause damage to the gener-
ator and power consumers connected to it.
The device generates electricity. Follow safety precautions
to avoid electric shock.
ATTENTION – DANGER!
It is forbidden to connect to the generator devices which
can generate current pulses and direct energy towards
the generator (voltage stabilizers, devices with electronic
brakes, on-grid and hybrid inverters, etc.).
IMPORTANT!
The generator should be used as an IT or TN system
based on the application. Earthing and additional pro-
tective measures such as insulation monitoring or pro-
tection against accidental contact (residual current de-
vice) must be provided based on the application and the
system used.
IMPORTANT!
- Do not let the presence of unauthorized persons, children or animals when working with generator. If
necessary, make sure to fencing the working area.
- Please use safety shoes and protective gloves when working with generator.

It is recommended to ground the generator before operating it for the first time. Before starting the device,
remember that the total power of the connected power consumers should not exceed the nominal power
of the generator.
TERMS OF USE OF INVERTER GENERATOR 4
Könner & Söhnen generators were initially designed
as an IT system with basic protection by insulation of
hazardous live parts according to DIN VDE 0100-410. The
generator housing is insulated from the current-carrying
L and N conductors. The generator must be grounded
in all cases, except for an IT system with an insulated
neutral wire and bonding. A grounded IT system requires
the use of an insulation monitoring device.
IMPORTANT!
Make sure that the control panel, the blinds and the
underside of the inverter are well cooled and protected
against the ingress of small solids, dirt, and water. Im-
proper operation of the cooler can cause damage to the
motor, inverter or alternator.
IMPORTANT!
GENERATOR OPERATION 5
OIL LEVEL INDICATOROIL LEVEL INDICATOR
When the oil level falls below the level required for operation, the oil level indicator lights up, and then the
engine stops automatically. The engine will not start until oil is added.
AC INDICATORAC INDICATOR
When the generator is running and producing electricity, the AC indicator light is on.
The overload indicator may light up within several sec-
onds after start-up or when connecting electrical devices
requiring a high starting current, such as a compressor
or voltage indicator. However, this is not a malfunction.
IMPORTANT!
OVERLOAD INDICATOROVERLOAD INDICATOR
The overload indicator lights up when the generator is overloaded, the inverter control unit overheats or
the AC output voltage rises.
If the overload indicator goes on, the engine will continue to operate, but the generator will no longer
produce electricity. In this case, you must perform the following steps:
1. Turn off all connected electrical appliances and stop the engine.
2. Reduce the total power of the connected devices until the nominal power of the generator is reached.
3. Check if the vent grid is clogged. Remove excess dirt or debris, if any.
4. After checking, start the engine.
FUEL INDICATOR (FOR DUAL-FUEL GENERATORS)FUEL INDICATOR (FOR DUAL-FUEL GENERATORS)
The indicator shows the type of fuel used to run the generator: green for LPG and blue for petrol.
DC FUSEDC FUSE
The DC protector automatically switches to “OFF” when the current of the operating electrical device is
higher than the rated current. To use this equipment again, turn on the DC fuse again by pressing the “ON”
button.
uk.koenner-soehnen.com |9

EARTHING BOLTEARTHING BOLT
In all cases, except for an IT system with an insulated neutral wire and bonding, the generator earthing bolt
must be connected to the grounding circuit with a flexible copper conductor with a cross-sectional area of
at least 6 mm2.
FUEL TANK CAP AIR VENTFUEL TANK CAP AIR VENT
(EXPECT FOR MODELS KS 5500(EXPECT FOR MODELS KS 5500iiES ATSR, KS 5500ES ATSR, KS 5500iiEG S)EG S)
The fuel cap is equipped with a vent for air supply to the fuel tank. When the
engine is running on petrol, the vent must be in the “ON” position (OPEN).
This will allow fuel to enter the carburetor for engine operation. After the
generator stops, allow it to cool down and close the air vent on the fuel
cap. When the generator is not in use, close the vent to the “OFF” position.
If the DC fuse turns o, reduce the load of the connected
electrical device. If the DC protector turns o again, stop
operation and contact your nearest Könner & Söhnen®
service center.

FUNCTIONAL DESCRIPTION
OF INVERTER GENERATORS 8
The generator is supplied with disconnected battery.
When using the generator for the rst time, open the
maintenance door and connect the battery line (g. 3).
For long-term storage of generator, disconnect the bat-
tery line (for models KS 5500iES ATSR, KS 5500iEG S).
IMPORTANT!
Fuel switch should only be performed with the load o.
IMPORTANT!
For models with electric start, check if the battery is charged. If necessary, recharge the battery with a
dedicated charger for lithium-ion batteries or start the generator with a manual start and allow it to run
idle while it is recharging.
“ON” MODE“ON” MODE
When the ECON switch is in the “ON” position, the control unit monitors the engine speed, reducing it
commensurate with the connected load. If the engine speed is not enough to generate electricity to provide
the load, the control unit will automatically increase the engine speed.
As a result, fuel consumption is optimized and noise levels are reduced.
It is forbidden to start the generator with the ECONOMY MODE ON. Economy mode
should be turned on only after starting the generator and only with a low load. Failure to
comply with this requirement may result in generator failure and void warranty repair.
“OFF” MODE“OFF” MODE
The ECON switch must be set back to “OFF” when using electrical devices requiring a high starting current,
such as a compressor or submersible pump.
4. For manual start turn MAIN POWER button to “ON” position, pull the manual starter until a slight
resistance is felt, then pull it toward you relatively sharply. Slowly turn the manual starter by hand, do not
release it abruptly.
4.1. For electric start - turn MAIN POWER button to “ON” position, then press the ELECTRIC START button.
Place the container with gas only vertically, according to
the instruction manual for gas cylinders. The horizontal
placement of gas cylinders leads to hybrid generator
gearbox failure.
