CJ-series PROFIBUS Master Unit Operation Manual for NJ-series CPU Unit (W509)
• We recommend replacing the Battery with the power turned OFF to prevent the CPU Unit’s sensitive
internal components from being damaged by static electricity and to prevent malfunctions. The Bat-
tery can be replaced without turning OFF the power supply. To do so, always touch a grounded piece
of metal to discharge static electricity from your body before you start the procedure.
After you replace the Battery, connect the Sysmac Studio and clear the Low Battery Voltage error.
• Make sure that the required data, including the user program, configurations, settings, variables, and
memory used for CJ-series Units, is transferred to a CPU Unit that was replaced and to externally
connected devices before restarting operation.
Be sure to include the routing tables, network parameters, and other CPU Bus Unit data, which are
stored in the CPU Unit.
