Removing the eAIB Chassis

Switch off the 200/240 VAC input supply to the chassis.
3.
Switch off the optional SmartController EX, if you are using one.
4.
Disconnect the 24 VDC supply cable from the chassis +24 VDC input connector. For the
connector location, see Figure 3-6.
5.
Disconnect the 200/240 VAC supply cable from the chassis AC Input connector.
6.
Disconnect the eAIB XSYSTEM cable from the chassis XSYSTEM connector.
7.
Disconnect any other cables, which may be connected to the chassis, such as XIO, RS-

8.
Using a 5 mm hex wrench, carefully unscrew the chassis securing screw, which is
shown in the following figure. Note that the screw does not need to be completely
removed in order to remove the chassis, as this screw is captured on the chassis heat
sink.
