CONNECTION
RS485 repeaters can be installed to increase the length of a segment.
NOTE
Observe the following cable installation rules:
Ø The bus cable must not be twisted, stretched or compressed during
installation.
Ø Supplementary constraints as regards electromagnetic compatibility must
also be observed.
Further relevant information can be found, for example, in Chapter 3 of the
Compendium (6SE7080-0QX50 Edition AE, MASTERDRIVES Document).

Comms Link Connector

To connect the PROFIBUS module to the inverter it will be necessary to insert the
Comms Link cable bus connector between the Inverter I/O board and the
PROFIBUS module.
The cable screening lead on the cable should be connected to the I/O board (see
Figure 4-7).
4.2.3

Connecting the Bus Cable

PROFIBUS connections to the module are made via cable glands. The cable
should be stripped back and made-off as shown in Figure 4-8.
Figure 4-8
PROFIBUS cables must be routed at least 20 cm (7.87 inches) from any power
cables.
