C Protective conductor rail
The protective conductor rail must also be connected over a large surface area to the mounting plates and
additionally with an external cable (cross-section at least 10 mm2 / 0,015 inch2) to the protective conductor system to
avoid interference currents.
D Protective conductor terminal block
The protective conductor terminal block must be connected to the protective conductor rail.
