6-3 Conformance to EC Directives
1,2,3...
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.
Applicable standard: EN 61131-2
The OMRON products described in this manual comply with the related EMC
Directives. To ensure that the machine or device in which the products are
used complies with EC Directives, the products must be installed as follows:
1. The products must be installed within a control panel.
2. A DC power supply with reinforced insulation or double insulation that can
maintain a stable output even if the input is interrupted for 10 ms must be
used for communications power, internal power, and I/O power. The
OMRON S82J-series Power Supply is recommended. (See note.)
3. Products complying with EC Directives also conform to the Emission Stan-
dards (EN 61131-2 and EN 61000-6-4). 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 equip-
ment complies with EC Directives.
4. Conformance with the EC Directives was confirmed with a system config-
uration using I/O wiring lengths of less than 30 m.
Note Conformance with the EMC Directive was confirmed when using
the recommended power supply.
