• Take appropriate and sufficient countermeasures when installing systems
in the following locations:
• Locations subject to static electricity or other forms of noise.
• Locations subject to strong electromagnetic fields.
• Locations subject to possible exposure to radioactivity.
• Locations close to power supplies.

6-2 Concepts
EMC Directives
The OMRON products described in this manual are designed so that they
individually comply with the related EMC Directives 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 Directives (see note). Whether the prod-
ucts conform to the standards in the system used by the customer, however,
cannot be checked by OMRON and 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 EMC (Electromagnetic Compatibility) standards are as follows:
EMS (Electromagnetic Susceptibility): EN 61131-2 and EN 61000-6-2
EMI (Electromagnetic Interference): EN 61131-2 and EN 61000-6-4
(Radiated emission: 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.
Applicable standard: EN 61131-2
6-3 Conformance to EC Directives
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:
1,2,3... 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.)
