Passive Components for RS-485 Networks

Keep to the permitted ambient conditions

Remember that a standard connecting cable cannot stand up to the same environmental conditions as an uninterrupted LAN cable. If necessary, provide extra protection for the connection to avoid dampness, dust or aggressive gases causing problems by covering the connection in a cable sleeve. You can find information about ordering this in Appendix I-2 “SIMATIC NET Support and Training”.
