Conformance to EC Directives 6
• Do not place heavy objects on top of the cables.
• Route cables inside conduits.
• Before touching the Unit, be sure to first touch a grounded metallic object
in order to discharge any static build-up.

6-2 Concepts
EMC Directives
OMRON devices that comply with EC Directives conform to the related EMC
standards so that they can be more easily built into other devices or
machines. The actual products have been checked for conformity to EMC
standards (see the following note). Whether the products conform to the stan-
dards 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 in which the OMRON devices are installed.
The customer must, therefore, perform final checks to confirm that devices
and the overall machine conform to EMC standards.
Note Applicable EMC (Electromagnetic Compatibility) standards are as follows:
EMS (Electromagnetic Susceptibility): EN50082-2
EMI (Electromagnetic Interference): EN61000-6-2
6-3 Conformance to EC Directives
The CS1W-SLK11 and CS1W-SLK21 SYSMAC LINK Units comply with EC
Directives. To ensure that the machine or device in which these SYSMAC
LINK Units are used complies with EC directives, the SYSMAC LINK Units
must be installed as follows:
1,2,3...
1. In order to conform with EC Directives, the SYSMAC LINK Units must be
installed within a control panel. Use an SA20-712 (made by NITTO ELEC-
TRIC WORKS) or a similar model.
2. Reinforced insulation or double insulation must be used for the DC power
supplies used for the communications and I/O power supplies.
3. SYSMAC LINK Units complying with EC Directives also conform to the
Common Emission Standard (EN50081-2). When a SYSMAC LINK Unit is
built into a machine, however, noise can be generated by switching devic-
es using relay outputs and cause the overall machine to fail to meet the
Standards, particularly with radiated emission for 10-m regulations. The
customer must, therefore, take measures to ensure and perform final
checks to confirm that devices and the overall machine conform to EMC
standards.
