This applies small parts such screws, rivets, and nameplates and to parts inside enclosure, irrespective their size (e. Solder connections are only permissible terminals which are suitable for soldering.) Parts which not require connection the protective earth system It not necessary connect exposed conductive parts the protective earth circuit when these parts are mounted that they not constitute a hazard because: - they cannot touched large surfaces grasped with the hand and they are small size (less than approximately mm) or - they are located that contact with live parts insulation failure is unlikely. General requirements All terminals, especially those the protective earth system, shall be secured against self-loosening. Every protective earth terminal point shall identified such, using the (CD) symbol 60417-IEC-5019. It not permissible connect protective conductors fittings used to attach connect appliances parts. electromagnets of contactors relays well mechanical parts devices).] The protective earth terminal points shall not have any other function. Two more conductors may connected terminals only the latter are designed for that purpose.
