Precautions for Safe Use
NJ-series NJ Robotics CPU Unit User’s Manual (W539)
• The Battery may leak, rupture, heat, or ignite. Never short-circuit, charge, disassemble, heat, or
incinerate the Battery or subject it to strong shock.
• Dispose of any Battery that has been dropped on the floor or otherwise subjected to excessive
shock. Batteries that have been subjected to shock may leak if they are used.
• UL standards require that batteries be replaced by experienced technicians. Make sure that an expe-
rienced engineer is in charge of Battery replacement.
• Apply power for at least five minutes before you change the Battery. Install a new Battery within five
minutes (at temperature of 25 ° C) after you turn OFF the power supply. If power is not supplied for at
least 5 minutes, the saved data may be lost.
• 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 starting 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/setup data, variables,
and memory used for CJ-series Units, is transferred to the new CPU Unit and externally-connected
devices before you restart operation. Be sure to include the routing tables, network parameters, and
other CPU Bus Unit data, which are stored in the CPU Unit.
• The disposal of the product and Batteries may be subject to local government regulations. Dispose of
the product and Batteries according to local ordinances as they apply.
• The following information must be displayed for all products that contain primary lithium batteries with
a perchlorate content of 6 ppb or higher when shipped to or transported through the State of Califor-
nia, USA.
