Battery Replacement Time Periods
If the robot is kept in storage and not in production, or the 24 VDC supply, is applied less than
half the time, while the encoder backup battery is in the robot, then the battery should be
replaced every 2 years.
If the robot is turned on with 24 VDC supplied to the robot more than half the time, then you
can increase the replacement interval to a maximum of 4 years.
NOTE: Dispose of the battery according to all local and national environmental
regulations regarding electronic components.
Battery Replacement Procedure
1.
Obtain the replacement battery pack.
2.
Switch off the 24 VDC input supply to the robot.
3.
Switch off the 200/240 VAC input supply to the robot.
4.
Switch off the optional SmartController EX, if you are using one.
5.
Disconnect the 24 VDC supply cable from the robot +24 VDC input connector. For the
connector location, see Figure 3-6.
6.
Disconnect the 200/240 VAC supply cable from the robot AC input connector.
7.
Using a 5 mm hex wrench, carefully unscrew the eAIB chassis securing screw. See Fig-
ure 6-8. 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.
8.
While holding the chassis heat sink, carefully and slowly lower the chassis down, see
Figure 6-9. This provides access to the battery pack, as shown in the following figure.
