Deinstalling the ET 200X
Note the following before deinstalling the ET 200X:
!
Caution
Before you deinstall expansion modules, you must switch off all the supply
voltages for the ET 200X (i.e. the ET 200X must be deenergized).
If you do not do this, when you remove the expansion modules their electronic
components can get damaged.
Note
If servicing is required, it is possible to eliminate a module fault by replacing the
upper section (the ET 200X must be in a deenergized state). In this case,
disassemble the replacement module and use the upper section.
This renders complete disassembly of the ET 200X unnecessary.
