NOTICE
Cable connection between VD devices
Use the same type of cable for the cable connection between two VD devices. Infrastructure
cables as well as any patch cables in use must be of the same cable type.
If the cable type between the two VD devices changes during the transmission path, signal
reflections can occur at the connection site of the different cables, which can result in frame
losses.
Note
For connection to electrical networks note the information in Appendix A.1 and A.2.

Using PROFIBUS standard cable GP
If you use a PROFIBUS standard cable GP, the wires must be stripped before they are inserted
in the FC connector.
Note
If you use cables with a length > 500 m, connection establishment can take up to 2 min.
Note
If you connect an MM992-2VD media module to existing PROFIBUS cabling, the same
requirements relating to shield contact and the lightning protection concept apply as for
PROFIBUS.
