V. Connecting electrical devices
and generator load-capacity
y
It is possible to connect electrical devices intended to be powered via the standard electrical power distribution grid
into the 230 V ~50 Hz and 400 V power sockets.
For powering electrical devices it is necessary to re-
spect the following conditions, otherwise the powered
electrical devices or the generator may be damaged:
The total nominal (operating) power input of all
the connected electrical devices must not exceed
the nominal (operation) electrical power out-
put of the generator. To determine the nominal
power input of an electrical device, it is possible
to use an affordable socket power input meter
(a wattmeter). The total operating (rated) power
output of the generator is understood to mean
the total drawn power input of all the electrical
devices connected to the generator at a voltage
of 230 V/400 V ~50 Hz.
Turn on (start / put into operation) electrical devi-
ces gradually one after the other with a time inter-
val in between and not all devices at the same
time. The large surge power input caused by all
the connected electrical devices being turned on
may cause a peak voltage spike and damage the
connected electrical devices.
The generator must not be concurrently used for
powering sensitive electrical devices (e.g. compu-
ter, TV, office equipment) and an electrical device
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" voltage spikes (fluctuations),
which may damage sensitive electrical devices.
In the event that the generator is used as a bac-
kup 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 con-
nected to a TN-C-S (TN-C) grid only via an overvol-
tage 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.

On the three-phase generators HERON® 8896414
or HERON® 8896412 the max power input of a con-
nected electrical device is limited by the electrical
power output going to the single phase, which is
always connected to only one of the three 230 V
power sockets. It is possible to plug an electrical
device with an operating power input of 1.9 kW into
one of the three 230 V power sockets of the three-
-phase generator. Thus for three power sockets 3×
1.9 kW (Max. power output is 3× 2.2 kW)- which
may be sufficient for a large number of electrical
devices, see table 3 and 4 below. It is not permitted
to power a three-phase electrical device from the
400 V power socket while simultaneously powering
a single-phase electrical device (devices) connec-
ted to the 230 V power socket (sockets) because
this would result in an asymmetrical load on the
phases, which could damage the generator.
y
The 230 V power sockets of the generators are
rated in the same way as standard 230 V power
sockets in mains power grids with a current load
capacity up to 16 A - thus from a single 230 V
power socket it is not permitted to draw a power
output greater than 3.5 kW. On generators with an
operating power output of 5.0 kW and greater, it
is thus not permitted to draw power output from
one 230 V power socket that is greater than 3.5 kW
(which, however, is a sufficiently hight power
input, see table 3 and 4 below). It is thus not
possible to use an extension cord with multiple
power sockets to power multiple electrical devices
from a single socket on the generator the combi-
ned drawn power input is greater than 3.5 kW.
In the event that it is necessary to
power an electrical device with a
power input greater than 3.5 kW,
then, to power such an electrical
device, use the generator HERON®
8896419 or HERON® 8896421 with an operating
power output of 6.3 kW, which is equipped with a
230 V~50 Hz power socket that is rated for a load
of 32 A with a circuit breaker set for 31.3 A and via
this power socket it is possible to power an electri-
cal device with a power input of 6.3 kW. This gene-
rator can thus be used with advantage to power
electrical devices that it is not possible to connect
to a standard mains power grid socket where there
is not an independent power circuit with a circuit
breaker rated for a current load greater than 16 A.
An example of such an electrical device are wel-
ding units with the ability to set welding currents
higher than 140 A, because when a higher welding
current than 140 A is set, the circuit breaker rated
for a current load of 16 A is disengaged, which is
quite normal in a standard electrical power grid.
