5.7 Replacing the eAIB Chassis
CAUTION:Follow appropriate ESD procedures during
the removal/replacement phases.
Removing the eAIB Chassis
1.
Switch off the 24 VDC input supply to the chassis.
2.
Switch off the 200/240 VAC input supply to the chassis.
Lock out and tag out power.
3.
Disconnect the 24 VDC supply cable from the chassis +24 VDC input connector.
4.
Disconnect the 200/240 VAC supply cable from the chassis AC Input connector.
5.
Disconnect the eAIB XSYSTEM cable from the chassis XSYSTEM connector.
6.
Disconnect any other cables, which may be connected to the chassis, such as Ethernet,
or any others.
7.
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.
Figure 5-2. Securing Screw on eAIB Chassis
8.
While holding the chassis heat sink, carefully and slowly lower the chassis down (see
the following figure), so that enough access is available to remove the internal cables.
The chassis can be laid flat or placed to the right side of the robot for better access.
