Conformance to EC Directives 6
6 Conformance to EC Directives
The Controller Link Units conform to EMC and Low Voltage Directives as fol-
lows:
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 (Electro-Magnetic Susceptibility) and EMI (Electro-Magnetic
Interference) standards in the EMC (Electro-Magnetic Compatibility) stan-
dards are as follows:
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 PLC (EN61131-2).
The Controller Link Units that comply with EC Directives (CVM1-CLK21,
C200HW-CLK21, CS1W-CLK21(-V1), CJ1W-CLK21(-V1), and CQM1H-
CLK21) must be installed as follows:
1,2,3...
1. The Controller Link Units are designed for installation inside control pan-
els. All Controller Link Units must be installed within control panels.
2. Use reinforced insulation or double insulation for the DC power supplies
used for the communications power supply and I/O power supplies.
3. The Controller Link Units that comply with EC Directives also conform to
the Common Emission Standard (EN61000-6-4). Radiated emission char-
acteristics (10-m regulations) may vary depending on the configuration of
the control panel used, other devices connected to the control panel, wir-
ing, and other conditions. You must therefore confirm that the overall ma-
chine or equipment complies with EC Directives.
