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 require that batteries be replaced only by experienced tech-
nicians. 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.
• Incorrect data link table or parameter settings may cause unexpected
operation. Even when the data link table and parameters have been set
correctly, do not start or stop the data link before verifying that it is safe to
do so.
• CPU Bus Units will be reset when the routing table is transferred from a
Programming Device to the PLC. (The Units are reset to ensure that the
new routing table data is read and enabled.) Do not transfer the routing
table before verifying that it is safe to do so, i.e., it is safe for the CPU Bus
Units to be reset.
• Install the Units properly as specified in the operation manuals. Improper
installation of the Units may result in malfunction.
6 Conformance to EC Directives
6-1 Applicable Directives
• EMC Directives
• Low Voltage Directive
6-2 Concepts
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:
EMS (Electromagnetic Susceptibility): EN61000-6-2
EMI (Electromagnetic Interference): EN61000-6-4
(Radiated emission: 10-m regulations)
Low Voltage Directive
Always ensure that devices operating at voltages of 50 to 1,000 V AC and 75
to 1,500 V DC meet the required safety standards for the PLC (EN61131-2).
