Rules for the configuration of the ET 200iSP in Zone 1
If you use the ET 200iSP in zone 1, then you must observe the following rules:
1. Install the ET 200iSP in an enclosure with degree of protection Ex e (increased safety) (see
section "Installation rules (Page 101)", see Appendix "Article numbers (Page 419)").
2. Disconnection of the PROFINET IO through the media converter (SCALANCE X 212-2 (see
Appendix "Article numbers (Page 419)") with optical safe transceiver. The media converter
guarantees protection in hazardous areas according to EN/IEC 60079-28. You can install the
media converter in the hazardous area of Zone 2 or in the safe area.
3. You can use normal PROFINET IO bus cables in hazardous areas (see Appendix "Article
numbers (Page 419)"). However, you must mark these as "Ex i bus cables" (e.g. attach blue
tape/blue shrink-on sleeve on the ends; mark the cable with blue color).
4. Connecting the fiber-optic cable to the IM 152-1PN using the LC plug (see Appendix "Article
numbers (Page 419)").
The maximum length of the PROFINET IO via fiber-optic cable is 3000 m.
