6.1 Disassembly and disposal
The disassembly of a CX20x0 hardware configuration with system interfaces takes
place in 3 steps
1. Switching off and disconnecting the power supply
Before a CX20x0 system can be dismantled, the system should be switched off, and the power supply
should be disconnected.
2. Removing from the DIN rail
Before the individual modules are disconnected, the whole CX20x0 hardware block should be removed from
the DIN rail. Proceed as follows:
2.1. Release and remove the first Terminal next to the power supply unit on the DIN
rail.
First remove any wiring from power supply unit and then from the first terminal on the DIN rail next to the
power supply unit. If the wiring is to be reused for another system, it is advisable to make a note of the
connections. Then pull the orange terminal release (see arrow) to release the terminal and pull it out.
2.2. Releasing the CX20x0 systems
In order to release the CX20x0 block, the DIN rail fastening above and below the device must be released.
To do this, press the hooks outwards using a screwdriver. An audible click indicates that the device is
released.
