To connect electrical devices to a 32 A power socket of
the generator it is necessary to replace the 16 A plug
of the power cable of the electrical device for a blue
power plug rated for a current load of 32 A (replace-
ment may only be performed by a qualified electrician).
y
The single-phase generator HERON® 8896411 has
an operating power output of 2.0 kW and genera-
tor HERON® 8896416 has an operating power out-
put of 2.5 kW, which is below the limit for the cur-
rent load capacity of a single 230 V power socket
rated to 16 A (3.5 kW).
The specified max. power output serves for very
short coverage of a higher current draw by a connec-
ted electrical device above the value of the continu-
ous (long-term) operating power output, e.g. when it
is turned on.

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 method of use of
the electrical device, 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 excep-
tional 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 out-
puts 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 vessel, 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 electrical devi-
ce), 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 alter-
nator of the generator is able to cover the peak
current surge.
y
In the event that a heating electrical device is
connected to the generator and the total power
draw approaches the operating electrical power
output of the generator, the specified electrical
power output of the generator may not necessa-
rily be achieved since in the case of connection of,
for example, a hot air gun with heat regulation a
change in the input to the heat gun of up to 300 W
per second may occur (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 fluctuations in power input in
the event that the total drawn power input appro-
aches the operating power output of the genera-
tor, and this is manifested in its reduced electrical
operating power output. 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 with an overlap of up to 30 %,
the type of electrical device (compressor with a
pressure vessel, etc.) and the number of intended
electrical devices that are to be powered from the
generator, since the power inputs of the individual
electrical devices are added up.
Before connecting the electrical device / electri-
cal devices to a generator, to get an overview,
check its power input using a standard wattmeter
(electricity consumption meter) during start up of
the electrical device and its expected load from
the el. power distribution grid.
y
In table 3, 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 purpose of use of the angle grin-
ders and requirements for the minimum electrical
power output of the generators.
Note
y
Tables 3 and 4 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 8896219 (1850
W/Max. 2000 W) has, compared to the previous model
HERON® 8896217 (1 600 W/max. 2000 W) a larger ope-
rating electrical 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.
