grounded on the instrument side. During an installation, all of the cables that are connected to the device must be free of energy. The device
must be protected against inadmissible humidity, vibrations, severe soiling and make sure that the operation temperature is not exceeded. All
input and output lines that are not connected to the supply network must be laid out as shielded and twisted cables. These cables should not be
close to the power cables or components. The installation and electrical connections must be carried on by a qualified staff and must be
according to the relevant locally applicable regulations.
