6.2.4 Protective Conductor Connection
In general, consider the following when connecting a protective conductor:
 Always connect the protective conductor.
 Use cable lugs for external protective conductor connection.
 Permanently install the protective conductor close to the enclosure.
 Connect all uncoated, non-energised metal parts to the protective conductor system.
 Neutral conductors have to be installed as live conductors.

6.2.5 Installation Conditions

During installation – wiring inside the terminal box – sufficient distance must be
maintained between the electrical lines themselves and between electrical lines and
components. This then provides sufficient insulation against voltage punctures in the
interior.
