HERON 8896230 Bersetzung Der Ursprünglichen Bedienungsanleitung Seite 105

 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 the
case of most electrical appliances, 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 method 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 mini-
mum required electrical power outputs of the generators
required to power them are provided in tables 2 and 3.
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 3),
since the more powerful alternator of the generator is
able to cover the peak (surge) current draw.
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
105
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, which manifests itself by a reduc-
tion in the electrical power output of the generator and
power input to the heat gun. A heat gun without tem-
perature 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
device, the year of manufacture of the electrical
device and the type of electrical device (compressor
with a pressure vessel, etc.) and the number of inten-
ded electrical devices that are to be powered from
the generator, since the power inputs of the indivi-
dual electrical devices are added up. The deciding
factor for the use of an electrical device with a power
input that is approaching the electrical power output
value of the generator should be the soft start func-
tion on the electrical device, which ensures a slower
ramp up of the electric motor and thereby reduces
the current spike that would otherwise not enable
the given electrical device to be used with the inten-
ded generator with a lower electrical power output.
y Before purchasing a generator or connecting an
electrical device/s to the generator, to get a general
ideal, first use a standard wattmeter (device for mea-
suring electrical power consumption) both during
the start up of the electrical device as well as when
placed under the expected load from the mains
power grid (see table 2 and 3) and if possible, check
the use of this electrical device/s on a sample of the
generator being considered, since a wattmeter may
not necessarily be able to capture the peak current
ramp-up the duration of which is less than a second.
y In table 2, there is a drawn up overview of the power
inputs of angle grinders with a cutting disc diameter
from 115 mm to 230 mm with the use of tools of the
provided specification according to the determined pur-
pose of use of the angle grinders and requirements for
the minimum electrical power output of the generators.
Note
y Tables 2 and 3 refer to the digital inverter generators
HERON® 8896216 and HERON® 8896217, which are not
part of our offer. The only reason why they are included
is that the described tests were performed on them
and they cannot be entirely compared to the respective
available models HERON® 8896218 and HERON® 8896219
for the following reasons. The current mode HERON®
8896218 (900 W/Max. 1 100 W) is equipped with better
electronics than model HERON® 8896216 and handles
loads better at full operating power output than the
original model HERON® 8896216. The current model
HERON® 8896219 (1850 W/Max. 2000 W) has compared
to the original model HERON® 8896217 (1 600 W/max.
2000 W) a higher electrical operating power output. The
described digital generator models HERON® 8896216
and HERON® 8896217 thus better express the required
minimum electrical power output for the given load.
