- Provide suitable back-up fuses, see chapter 5 "Technical Data".
- Use only isolated cables and conductors whose testing voltage is AC 500V and whose
minimum quality is HO5 in intrinsically safe circuits.
- The diameter of one conductor must not be smaller than 0.1 mm; this applies also to
the individual wires of finely stranded conductors.
- EEx i - electric circuits are connected to blue terminal blocks.
- The consumers must be protected against overload independently of it.
