In accordance with DIN 60079-14 (VDE 0165-1), intrinsically safe circuits, the ends stranded and fine-stranded conductors must be
protected against splaying (e., via cable lugs ferrules) the type terminal blocks used.
WAGO recommends gas-tight tinned copper ferrules tinned copper pin terminals when connecting fine-stranded conductors terminal
blocks corrosive atmospheres.
