PROFIBUS Connections
(Panel Mount Enclosure)
The PROFIBUS connection to the Panel Mount enclosure is made using a straight
nine-pin connector. The connector will extend through the cutout in the back panel
of the terminal. This connector (or an equivalent) is a standard METTLER TOLEDO
part # 64054361. The connector is not supplied by METTLER TOLEDO as part of
the option.
Attach the nine-pin mating plug to the connector. Pin assignments are shown in
Figure 2-75. Follow the wiring instructions included with the connector to terminate
the wires.
Figure 2-76 shows the PROFIBUS board used in panel mount installations, with
the appropriate connector circled.
Figure 2-77 shows (from left to right) the module installed in the panel mount
enclosure, with the connector attached, and the rear panel in place.
