Conformance To Ec Directives - Omron CS1W-FLN22 Operation Manual

Conformance to EC Directives

6 Conformance to EC Directives
6-1 Applicable Directives
6-2 Concepts
• Check the user program and set parameters for proper execution before
actually running it on the Unit. Not checking the program may result in
unexpected operation.
• Observe the following precautions when wiring the communications
cable.
• Separate the communications cables from the power lines or high-ten-
sion lines.
• Do not bend the communications cables past their natural bending ra-
dius.
• Do not pull on the communications cables.
• Do not place heavy objects on top of the communications cables.
• Always lay communications cable inside ducts.
• Use appropriate communications cables.
• 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.
• 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 PLC (including changing the Star-
tup Mode setting).
• Force-setting/force-resetting any bit in memory.
• Changing the present value of any word or any set value in memory.
• Check that data link tables and parameters are properly set before start-
ing operation. Not doing so may result in unexpected operation. Even if
the tables and parameters are properly set, confirm that no adverse
effects will occur in the system before running or stopping data links.
• Install the FL-net Units separated sufficiently from devices that generate
high-frequency noise.
• Do not drop the FL-net Unit or subject it to excessive shocks or vibrations.
• EMC Directives
• Low Voltage Directive
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.
