1718 Ex I/O
Requirements for wires, stranded conductors, and wire end ferrules.
IMPORTANT
Use the terminal blocks from the range of accessories. For more
information, see Accessories in Chapter 1 of the 1718 Ex I/O User Manual,
publication
.
WARNING:
A spark can be generated by bare, conductive parts such as loose wire
ends, which can cause explosive mixtures to ignite.
• Stranded conductors must always be used with wire end ferrules. We recommend
using wire end ferrules approved according to DIN 46228-4.
