5.1. Use of alternating current
AC powered electrical equipment may be connected according to their
power requirements.
Rated power - the maximum power of the generator produced in a
continuous mode
Maximum power - generator power that can be produced for a short time
(e.g. temporarily to start devices with an increased inrush current)
The total power demand of the devices connected to the generator should
not exceed the rated power of the generator. To calculate the demand for
rated power, add the rated powers of the devices. Do not connect devices
whose rated power exceeds the rated power of the generator. Select the
connected devices so that the sum of their rated power does not exceed the
ratedpower of thegenerator.

14
The rated power of the device should be specified in the operating manual,
if this information is not provided, multiply the current by the voltage.
Power [W] = Voltage [V] x Current [A]
Connecting devices:
1. Wait a while before connecting electrical appliances to the generator.
2. Make sure the devices are turned off.
3. Connect the devices to the appropriate inputs (230V or 400V).
3 Switch on the devices, starting with those with the greatest power
demand.
Do not connect devices that require electricity with a frequency
60Hz.
Do not connect single-phase and three-phase devices at the same
time
5.2 Use of direct current
The DC connection is only intended for recharging car batteries
with a voltage of 12V. Do not use the generator to start the car!
Failure to follow procedures could cause the battery to explode and
seriously injure people nearby. Keep the battery away from heat,
fire, sparks, andflammable materials.
In order to properly connect the battery to the DC socket:
1. Connect one of the charging leads to the positive end of the battery and
the other lead to the negative end.
2. Connect the free end of the positive cable to the positive output on the
generator.
3. Connect the free end of the negative cable to the negative output on the
generator.
4. Turn on the generator.
5. After charging, disconnect the wires from the generator first, then from
the battery.
