Conformance to EC Directives 6
• Do not pull on the communications cables or bend the communications
cables beyond their natural limit. Doing either of these may break the
cables.
• Do not place objects on top of the communications cables or other wiring
lines. Doing so may break the cables.
• Before touching a Unit, be sure to first touch a grounded metallic object in
order to discharge any static built-up. Not doing so may result in malfunc-
tion or damage.
• When transporting or storing Units, place them in special packing boxes
and do not allow them to be subject to excessive shock or vibration during
transportation.
• Confirm that no adverse effect will occur in the system before attempting
any of the following. Not doing so may result in an unexpected operation.
• Changing the operating mode of the PC.
• Force-setting/force-resetting any bit in memory.
• Changing the present value of any word or any set value in memory.

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 Conformance with the EMC (Electromagnetic Compatibility) standards for
EMS (Electromagnetic Susceptibility) and EMI (Electromagnetic Interference)
vary with the model in the way shown below.
Low Voltage Directive
Always ensure that devices operating at voltages of 50 to 1,000 VAC and 75
to 1,500 VDC meet the required safety standards for the PC (EN61131-2).
