Electrical installation
Typ 8750
10.2. Electrical installation PROFIBUS DP
Procedure:
→ Connect the process controller according to the following tables.
The electrical connection module of Type 8693 features a setscrew
with nut which is used to connect the Technical Earth (TE)
(see “Fig. 13: Connection with PROFIBUS DP”).
→ Connect setscrew (TE connection) to a suitable grounding point.
To ensure electromagnetic compatibility (EMC), ensure that the
cable is as short as possible (max. 30 cm, Ø 1.5 mm
2
).
When the operating voltage is applied, the process controller is
operating.
→ Now make the required basic settings and actuate automatic
adjustment of the process controller, as described in
Chapter “13. PROFIBUS DP start-up”, page 35.
The settings in the BUS.COMM menu option are described
in Chapter “13. PROFIBUS DP start-up”.
