4.2.2 Installing the DIN rail
Uniform Installation
All the information in this section applies to both the DIN rail and the rail for active bus
modules.
Mounting Rail for Active Bus Module
To configure an ET 200M with the function "Module change during operation",
"Redundancy", use the associated rails with the order number 6ES7195-1Gxx0-0XA0. Only
these rails can take the active bus modules.
For the dimensions of the mounting rails for active bus module, refer to the chapter
"Installing Active Bus Modules and Modules (Configuration with Active Bus Modules)
(Page 66)".
Do you want to install a 2-meter rail?
If not, you can skip this section and read on from "Dimensioned Drawing for Fixing Holes".
If you do you need to prepare the 2-meter rail for installation. Proceed as follows:
1. Shorten the 2-meter rail to the required length.
2. Mark out:
– four holes for fixing screws (dimension: refer to the following figure and following table)
– One hole to take the fixing screw for the protective conductor.
3. Is the rail longer than 830 mm?
– If not: No further steps have to be taken.
– If so: Then, in order to stabilize the rail you must provide additional holes for extra
fixing screws. Score out these extra holes across the groove in the central area of the
rail (refer to following figure). These additional holes should be at approx. 500 mm
intervals.
4. Drill the marked holes with a diameter of 6.5
+0.2
mm for M6 screws.
5. Screw in an M6 screw to fix the grounding wire.
