4.6.6 Terminals for outer conductors
To connect the outer conductors to the terminals in hazardous areas, observe EN 60079-14 (Explosive
atmospheres - Part 14: Design, selection and installation of electrical systems).
Connect the conductors according to the terminal assignment. Equipotential bonding is not
necessary because the power supply is electrically isolated.
