Turn on (put into operation) the connected
electrical devices gradually one by one with
a time delay and not all the electrical devices at
the same time, which is important particularly
in the case where the total drawn power input
of the connected electrical devices is approa-
ching or equal to the nominal electrical power
output of the generator. The large surge power
input caused by all the connected electrical
devices being turned on at the same time may
cause a peak voltage spike and damage the
connected electrical devices.

To be safe, it is better to connect sensitive
electrical devices such as computers, TVs, offi-
ce equipment, etc. via overvoltage protection.
Extension cords with sockets having overvol-
tage protection can be purchased in stores.

The generator must not be concurrently used
for powering sensitive electrical devices (e.g.
computer, TV, office equipment) and an appli-
ance with a power electric motor, which has an
impulse ramp-up power input and fluctuating
power input based on the load placed on the
electric motor such as for example hand power
tools, etc. since this may result in "peak" vol-
tage spikes (fluctuations), which may damage
sensitive electrical devices.

In the event that the generator is used as
a backup electrical energy source for powering
TN-C-S (TN-C) networks (i.e. fixed electrical
grids in apartments, etc.), the connection of
the generator must be performed only by an
electrician with the necessary qualifications,
since it must be put into balance with the IT
network of the generator with the TN-C-S (TN-
C) grid. The generator may be connected to
a TN-C-S (TN-C) grid only via an overvoltage
protection that is built into the TN-C-S (TN-C)
grid. In the event of damages resulting from
non-professional connection, the manufacturer
of the compressor bears no responsibility
INFORMATION ABOUT POWER INPUT
OF ELECTRICAL DEVICES

ATTENTION
y
The power input specified on the rating label of the
electrical device containing an electric motor is, in most
cases, the expression of the power of the electric motor,
i.e. the load that the electric motor can handle rather
than expressing the power input during standard met-
hod of use of the electrical appliance, since the value of
the power input increases with the load placed on the
electric motor.
Power electric motors in hand power tools have
a starting ramp up input power, which is greater than
the power input when a standard load is applied to the
electric motor, however, most of the time it does not
reach the power input specified on the rating label of
the electrical device or in exceptional circumstances
exceeds it by up to 30 % of the stated value. When
a standard operating load is applied to hand power
tools, the power input is below the value specified on
the rating label. For illustration, the starting power
inputs and power inputs during standard use of certain
power tools and the minimum required electrical power
outputs of the generators required to power them are
provided in tables 3 and 4.
y
A typical example of electrical devices that differ from
the above-mentioned are those having a higher peak
current draw, such as compressors with a pressure ves-
sel, high pressure washers with a higher power input
and likewise this may apply to certain electrical devices
with electrical motors with an older year of manufacture
(see the serial number on the rating label of the electri-
cal device), the powering of which requires the selection
of a generator with an approximately 1 to 2 kW greater
electrical power output than the power input specified
on the rating label of the electrical device (see table 4),
since the more powerful alternator of the generator is
able to cover the peak (surge) current draw at the start
up of these electrical devices.
y
In the event that a heating electrical device is connected
to the generator and the total power draw approaches
or is equal to the operating electrical power output of
the generator, the specified electrical power output of
the generator may not necessarily be achieved since,
for example, a hot air gun with heat regulation has
extremely rapid fluctuations in power input of up to
300 W per second (this behaviour also occurs when it is
powered from the mains power grid) and the generator
may not necessarily be able to handle such rapid fluctu-
ations in power input in the event that the total drawn
power input approaches or is equal to the operating
power output of the generator, and this is manifested
in a reduced electrical power output of the generator.
A hot air gun without temperature regulation normally
has a stable power input and this behaviour should not
occur with it.
y
When selecting a generator based on its electrical
power output, the deciding factor is the power input
value specified on the rating label of the electrical
