Conformance to EC Directives 6
• 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.
• After connecting Power Supply Units, CPU Units, I/O Units, Special I/O
Units, or CPU Bus Units together, secure the Units by sliding the sliders at
the top and bottom of the Units until they click into place. Correct opera-
tion may not be possible if the Units are not securely properly. Be sure to
attach the end cover provided with the CPU Unit to the rightmost Unit. CJ-
series PLCs will not operate properly if the end cover is not attached.
• 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.

EMC Directives
OMRON devices that comply with EC Directives also conform to the related
EMC standards so that they can be more easily built into other devices or the
overall machine. The actual products have been checked for conformity to
EMC standards (see the following note). Whether the products conform to the
standards in the system used by the customer, however, must be checked by
the customer.
EMC-related performance of the OMRON devices that comply with EC Direc-
tives will vary depending on the configuration, wiring, and other conditions of
the equipment or control panel on which the OMRON devices are installed.
The customer must, therefore, perform the final check to confirm that devices
and the overall machine conform to EMC standards.
Note Applicable EMC (Electromagnetic Compatibility) standards are as follows:
