Removal and disposal
A CX10x0 hardware configuration is dismantled in 2 stages:
0. Switching off and disconnecting the power supply
Before a CX10x0 system can be dismantled, the system should be switched off, and the power supply should be
disconnected.
1. Removing from the top-hat rail:
Before the individual CX10x0 modules are disconnected, the whole CX1020 hardware block should be removed from
the top-hat rail. Proceed as follows:
1.1. 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.
1.2. Releasing the CX10x0 system
In order to release the CX10x0 block, pull the white straps at the bottom of the module in the direction of the arrows.
They will lock in the extended position. After pulling the terminal release of the power supply unit, the block can be
removed carefully from the top-hat rail.
