4. When connecting the device to other devices (e.g. the PC) the interconnection has to be designed most

thoroughly, as internal connections in third-party devices (e.g. connection of ground with protective earth)
may lead to undesired voltage potentials.

5. The device must be switched off and must be marked against re-starting, in case of obvious malfunctions
