3. Note that the starting consumption of
devices driven by electric engines is
generally a multiple of the specified
rating. If in doubt, it is advisable to
contact the equipment manufacturer
directly.
The maximum current specified for each
socket must not be exceeded.
If normal cooling cannot be maintained,
or the operating conditions are
unacceptable in other respects, reduce
the consumption, rather than operating
the generator right up to its rating.
Ideal operating conditions are:
1. Ambient temperature: 25 °C
2. Air pressure: 100 kPa (1 bar)
3. Relative humidity: 30%
Do not operate the generator at ambient
temperatures above 40 °C, below –10 °C,
or in direct sunlight.
More detailed instructions for operation
under unfavourable conditions can be
found in the combustion engine manual.
11.5 Testing insulation monitoring/
startup/device connection
Testing insulation monitoring
Attention
Do not start the generator until you have
fully read and thoroughly understood
the safety precautions and operating
instructions in this manual.
During operation, check at least once a
day that the protective measure for the
risk of electric shock through indirect
contact (in accordance with DIN and
GW 308 requirement for Protective
isolation with insulation monitoring and
circuit breaking) is working properly.
With the engine running, carry out the
following test:
1. Unplug all devices connected to the
generator; open the glass cover and
switch the circuit breaker to ON/I.
2. Press the red test button.
3. Check whether the circuit breaker
releases and red the INSULATION
FAULT indicator lamp lights up.
4. Press and hold down the green reset
button for at least 2 seconds – the red
indicator lamp must go out.
5. Switch the circuit breaker to ON/I; close
the glass cover (tighten the knurled
screws by hand); the generator is now
ready for use.
Attention
The generator may only be used if the
circuit breaker released during the test
and the indicator lamp came on until the
reset button was pressed.
Setting the range switch
Turn the range switch to the required
position:
1st position:
Compressed air and electrical power,
variable engine speed.
* Compressed air and electrical power
can be consumed up to maximum
engine speed.
Note that engine speed is reduced in the
event of an overload.
* Compressed air mode without
consumption of electric power:
–> engine speed matched to demand
* Additional consumption of electric power
–> variable engine speed is matched
to consumption automatically, up to
maximum speed
* Automatic no-load operation, i.e. the
engine continues to run at maximum
speed for 100 seconds, if the electrical
power consumption is less than 75 VA
for a brief period.
2nd position:
As 1st position, but with the engine
running at constant speed
* Same functions as for 1st position, but
with the engine running at constant,
maximum speed
3rd position(only for 8 kVA and 12 kVA)
Fuel economy mode
Electrical power/no compressed air,
variable engine speed
* Electrical power only
* No air consumption possible
* Compressor pressure relieved, i.e. lower
fuel consumption due to the reduced
power consumption of the compressor
(only about 12 kVA)
* When electrical power being consumed
–> engine speed is matched to
consumption automatically, up to
maximum speed
* Automatic no-load operation, i.e., the
engine continues to run at maximum
speed for 100 seconds, if the electrical
power consumption is less than 75 VA
for a brief period.
4th position (only for 8 kVA and 12 kVA)
As 3rd position, with the engine running
at constant speed
* Same functions as described for 3rd
position, but with the engine running at
constant, maximum speed
Switching on

Danger
Follow safety precautions!
* Carry out the usual checks (safety
precautions, installation location, oil
level, fuel, etc) before using the
machine.
* Ensure that all the devices on the
generator output sockets have been
disconnected.
Note
All device switches must be in the
AUS / 0 / OFF position.
Danger
Unchecked devices may endanger
personnel on startup, and may be
damaged or cause damage.
* Start the generator.
Note
Do not load the generator until the
engine has warmed up.
* Check that the circuit breaker is
engaged in the ON / I position
(close the glass cover).
