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 Directives 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: Within the EMC (Electromagnetic Compatibility) standards, the applicable EMS
(Electromagnetic Susceptibility) standard is EN61000-6-2 and the applicable EMI
(Electromagnetic Interference) standard is EN61000-6-4 (10-m regulations.)
•
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 (EN61131-2).
•
Conformance to EC Directives
The CS1W-CIF31 USB-Serial Conversion Cables comply with EC Directives. Observe
the following precautions to ensure that the machine or device in which the Conversion
Cable is used complies with EC directives:
1. The CS1W-CIF31 USB-Serial Conversion Cable must be installed within a control
panel.
2. Reinforced insulation or double insulation must be used for the DC power supplies
providing the communications power supply and I/O power supplies.
3. CS1W-CIF31 USB-Serial Conversion Cables complying with EC Directives also
conform to the Common Emission Standard (EN61000-6-4). Radiated emission
characteristics (10-m regulations) may vary depending on the configuration of the
control panel used, other devices connected to the control panel, wiring, and other
conditions. You must therefore confirm that the overall machine or equipment
complies with EC Directives.
