You must also provide an acceptable grounding path for each device in your application. For
more information on proper grounding guidelines, refer to the Industrial Automation Wiring
and Grounding Guidelines, publication
1770-4.1 .
Battery Status Check
The DataSite controller uses a lithium battery that allows the real-time-clock (RTC) to
maintain the correct time setting through periods when line power has been removed from
the unit.
Current drain on the battery during these periods is approximately 1 microamp, and the
battery should provide approximately 10 years of operation for the RTC without power
applied.
The DS Settings Utility provides a display of the battery voltage. If the battery voltage should
drop below 2.0 V, contact Rockwell Automation Technical Support (see the back page for
contact information) to arrange for repair/exchange of the DataSite unit.
WARNING
The lithium battery is not user replaceable.
