> DO NOT connect or disconnect sensors, probes or test leads, as these parts are connected to a voltage
supply unit.
> The system is grounded via a protective conductor in the power supply cord. To avoid electric shocks,
the protective conductor has to be connected with the ground of the power network. Before connecting the input
or output connectors of the system, make sure that there is a proper grounding to guarantee
potential free usage. For countries, in which there is no proper grounding, please refere to your local
legally safety regulations for safety use.
DC systems: Every DC system has a grounding connected to the chassis (yellow/green safety banana
plug).

Adverse environmental conditions are:
> Moisture or high humidity
> Dust, flammable gases, fumes or dissolver
> Thunderstorm or thunderstorm conditions (except assembly PNA)
> Electrostatic fields, et cetera.
> Any direct voltage output is protected with a fuse against short cut and reverse-polarity, but is NOT
galvanically isolated (except it is explicit marked on the system).
> The system must be connected and operated to an earthed wall socket at the AC mains power supply
only (except for DC systems).
> Any other use than described above may damage your system and is attended with dangers like shortcut,
