Connect the devices to the output
sockets one after the other, ensuring
that the current specified for each socket
is not exceeded, and the generator is
not overloaded.
Note
Turn the devices on, one after the other,
using the device switches.
If possible, plug in/switch on devices
with high startup currents first. Only
connect suitable equipment in perfect
condition to the generator.
Switching off
* Turn the devices off, one after the other,
using the device switches.
Note
If possible, switch devices with the
highest current consumption off last.
* Switch the devices off one after the
other.
Note
Ensure the covers of unused sockets
are closed again properly.
Figure 35
* Allow the engine to continue running for
about 2 minutes, so that the generator
cools down.
* Stop the generator.
