6 Conformance to EC Directives
1, 2, 3...
• Check the user program for proper execution before actually running it on the
Unit. Not checking the program may result in an unexpected operation.
• 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 PC.
• Force-setting/force-resetting any bit in memory.
• Changing the present value of any word or any set value in memory.
• Do not pull on the cables or bend the cables beyond their natural limit. Doing
either of these may break the cables.
• Do not place objects on top of the cables. Doing so may break the cables.
• When replacing parts, be sure to confirm that the rating of a new part is correct.
Not doing so may result in malfunction or burning.
• Before touching the Unit, be sure to first touch a grounded metallic object in
order to discharge any static built-up. Not doing so may result in malfunction or
damage.
The CVM1D PCs conform to EMC and Low Voltage Directives as follows:
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 stan-
dards in the system used by the customer, however, must be confirmed 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 cus-
tomer must, therefore, perform the final check to confirm that devices and the
overall machine conform to EMC standards.
Note Applicable EMC (Electromagnetic Compatibility) standards are as follows:
EMS (Electromagnetic Susceptibility):
EMI (Electromagnetic Interference):
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 PC (EN61131-2).
The CVM1D, CVM1, and CV-series PCs that comply with EC Directives must be
installed as follows:
1. The CVM1D, CVM1, and CV-series PCs are designed for installation inside
control panels. All PCs must be securely grounded 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 CVM1D, CVM1, and CV-series PCs that comply with EC Directives also
conform to the Common Emission Standard (EN50081-2). Radiated emis-
sion characteristics (10-m regulations) may vary depending on the configu-
ration 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.
