passive ventilation system. This system requires the unit to be mounted correctly. Ventilation openings are
located at the top and bottom of the housing. The system can be installed in the following positions:

4.1.3 Mechanical installation of the UPS Module
Note
The power fail signal
The UPS module for CX90x0 is not fully supported by TwinCAT yet.The UPS module
should be connected the described way. To get the power fail signal (pin 3 on UPS) must
be connected to a digital input terminal. In this way the PLC can access the power fail sig-
nal and save the data or shut down the system. The shutdown time can only be set by the
selector on the front side of the UPS (best choice is 0).In case of shutdown the UPS will
restart the system after power fail.
0. Switching off and disconnecting the power supply
Before a CX90x0 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 CX90x0 modules are disconnected, the whole CX90x0 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.
