PROFIBUS connection
WARNING
Electric shock during connection while voltage is present
When connecting the PROFIBUS cable while voltage is present, there is a danger of
coming into contact with live components behind the terminal.
Touching live components can result in death or serious injury.
• Only connect the PROFIBUS cable to connector X126 when the unit is in a de-
energized state.
Position of PROFIBUS connection and diagnostics LEDs
The PROFIBUS connection and diagnostics LEDs are located on the Control Unit (CUD).
The PROFIBUS connection is via a 9-pin Sub-D socket X126. The connections are
electrically isolated.
See also Figure 6-44 Terminal/connector arrangement on the "Control Unit (CUD)"
(Page 156) and Chapter "Description of the LEDs on the CUD (Page 635)".
