The PROFIBUS standard suggests that both ends of the transmission line should be connected to
safety earth. If you do this, ensure that differences in local earth potential do not allow
circulating currents to flow, as not only can these induce large common mode signals in the data
lines, but they can also produce potentially dangerous heating in the cable. If in doubt, earth the
shield at only one section of the network.

• If the drive is at the end of the network it
must have terminating resistors.
• All other drives in the system should not
have terminators.
Connect terminating resistors to the last drive
as shown opposite. (All resistors ±5%,
minimum ¼ Watt).
