DIN VDE 0113 and VDE 0197 differ according and PE: because there degree freedom when designing the functional earth, but the protective earth must be conform with clear requirements. 1010010000 Order No.5/4AN WS Order No. terminal blocks which are intended protect human life must labelled green-yellow. The same applies for couplings grounding lines inside equipment these must also discharged.Functional earthing (PE terminals) Functional earth Functional earth The functional earth equipotential bonding mechanism that used discharge shield-coupled transient currents.

This creates so-called “clean“ earth because compensation currents are not possible when this type of wiring used. It can also have earth function prevent sensitive devices from damage.5 WS ≤ 2.151282250000 2012/2013 . such case, the key low-impedance connection. They can still used for functional earthing although. These terminals are easily identified through their colouring, showing that the circuits are only there functionally protect the electrical systems that are connected. Symbol for functional earthing TS 35 WPE 2. White terminals (FE) can used the functional earth. contrast to the protective earth, meshing not useful for the functional earth: instead wiring star topology makes more sense. For systems where this distinction must should be made, Weidmüller offers white terminal blocks from the and Z-series. Even the symbols used here have been extended order clarify the functional earth
