Ec Directives - Omron WIRED REMOTE I-O System Manual

EC Directives

6 EC Directives
1, 2, 3...
Use crimp terminals for wiring. Do not connect bare stranded wires directly to
terminals. Connection of bare stranded wires may result in burning.
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 a 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 dam-
age.
Remote I/O products conform to EMS and low-voltage level directives as fol-
lows:
EMC Directives
OMRON devices that comply with EC Directives also conform to the related
EMC standards, so that they can more easily be built in to other devices or the
overall machine. The actual products have been checked for conformity to EMC
standards. Whether they 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 cus-
tomer must, therefore, perform the final check to confirm that devices and the
overall machine conform to EMC standards.
Low-voltage Level Directives
Always ensure that devices operating at voltages of 50 to 1,000 VAC and 75 to
1,500 VDC meet the necessary safety standard for the PC (EN61131-2).
DeviceNet products that comply with EC Directives must be installed as follows:
1. Remote I/O Units are designed for installation inside control panels. All Re-
mote I/O 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, internal circuit power supply,
and the I/O power supplies.
3. Remote U/O products that comply with EC Directives also conform to the
Common Emission Standard (EN50081-2). Radiated emission characteris-
tics (10-m regulations) may vary depending on the configuration of the con-
trol 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.
4. Remote I/O products that comply with EC Directives have configurations
with less than 30 m of I/O wiring, and less than 10 m of power supply wiring.
