Omron CS1W-ETN21 Conformance to EC Directives, Applicable Directives, Concepts, EMC Directives

Conformance to EC Directives 6

•Check the user program 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 the setting of the startup operation mode).

•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 Applicable EMS (Electromagnetic Susceptibility) and EMI (Electromagnetic Interference) Standards in the EMC (Electromagnetic Compatibility) stan- dards are as follows:

Unit/Board	EMS	EMI
CS1W-ETN21	EN61000-6-2	EN61000-6-4
		(Radiated emission: 10-m
