RS485-Bus connection X6
A shielded 2-core twisted-conductor cable is recommended. Connect
one conductor to -X5/A (signal A) and one conductor to -X5/B (signal B)
using screw-type terminals, or connect the standard bus cable e.g.
7XV5103 to the 9-pin subD socket. To guarantee a trouble-free use of
the converter according to the specified characteristics, set the cable
screen on one side of the cable to the earth potential.
If possible, use a metallic SUB-D connector on the opposite side to
connect to the earth potential. If this is not possible connect the cable
screen on a screen track or a earhted mounting track with a fitting clamp.
