6.1 Disassembly and disposal
A CX9020 hardware configuration is dismantled in 2 stages:
1. Switching off and disconnecting the power supply
Before a CX9020 system can be dismantled, the system should be switched off, and the power supply
should be disconnected.
2. Removing from the top­hat rail:
Before the individual modules are disconnected, the whole CX9020 hardware block should be removed from
the top­hat rail. Proceed as follows:
2.1. Release and remove the first Terminal next to the power supply unit on the top­
hat rail.
First remove any wiring from power supply unit and then from the first terminal on the top­hat 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 CX9020 systems
To release the CX9020 block, release the orange DIN rail bracket on the left­hand side of the device. Push
