• Do not connect pin 6 (+5 V power supply line) of the RS-232C port on the
CPU Unit to any external device except the CJ1W-CIF11 RS-422A
Adapter, NT-AL001 RS-232C/RS-422A Adapter, or NV3W-M@20L Pro-
grammable Terminal. Doing so may damage the external device or CPU
Unit.
• When replacing parts, be sure to confirm that the rating of a new part is
correct. Not doing so may result in malfunction or burning.
• Before touching a Unit, be sure to first touch a grounded metallic object in
order to discharge any static build-up. Not doing so may result in malfunc-
tion or damage.
• When transporting or storing circuit boards, cover them in antistatic mate-
rial to protect them from static electricity and maintain the proper storage
temperature.
• Do not touch circuit boards or the components mounted to them with your
bare hands. There are sharp leads and other parts on the boards that
may cause injury if handled improperly.
• Do not short the battery terminals or charge, disassemble, heat, or incin-
erate the battery. Do not subject the battery to strong shocks. Doing any
of these may result in leakage, rupture, heat generation, or ignition of the
battery. Dispose of any battery that has been dropped on the floor or oth-
erwise subjected to excessive shock. Batteries that have been subjected
to shock may leak if they are used.
• UL standards required that batteries be replaced only by experienced
technicians. Do not allow unqualified persons to replace batteries.
• Dispose of the product and batteries according to local ordi-
nances as they apply. Have qualified specialists properly
dispose of used batteries as industrial waste.
• With a CJ-series PLC, the sliders on the tops and bottoms
of the Power Supply Unit, CPU Unit, I/O Units, Special I/O Units, and CPU
Bus Units must be completely locked (until they click into place). The Unit
may not operate properly if the sliders are not locked in place.
• With a CJ-series PLC, always connect the End Plate to the Unit on the
right end of the PLC. The PLC will not operate properly without the End
Plate
• Unexpected operation may result if inappropriate data link tables or
parameters are set. Even if appropriate data link tables and parameters
have been set, confirm that the controlled system will not be adversely
affected before starting or stopping data links.
• CPU Bus Units will be restarted when routing tables are transferred from
a Programming Device to the CPU Unit. Restarting these Units is required
to read and enable the new routing tables. Confirm that the system will
not be adversely affected before allowing the CPU Bus Units to be reset.
