7. Decomissioning
Disassembly and disposal
A CX50x0 hardware configuration is dismantled in 2 stages:
1. Switching off and disconnecting the power supply
Before a CX50x0 system can be dismantled, the system should be switched off, and the power supply should be
disconnected.
2. Removing from the top-hat rail:
Before the individual modules are disconnected, the whole CX50x0 hardware block should be removed from the top-
hat 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 top-hat 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 CX50x0 systems
To release the CX50x0 block, release the orange DIN rail bracket on the left-hand side of the device. Push back the
lower hook. An audible click indicates that the device is released.
After pulling the terminal release of the power supply unit, the block can be removed carefully from the top-hat rail.
