Conformance to EC Directives 6
• Use only the specified communications cables.
• Do not extend connection distances beyond the ranges given in the spec-
ifications.
• Observe the following precautions when wiring the communications
cable.
• Separate the communications cables from the power lines or high-ten-
sion lines.
• Do not bend the communications cables past their natural bending ra-
dius.
• Do not pull on the communications cables.
• Do not place heavy objects on top of the communications cables.
• Always lay communications cable inside ducts.
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.

EMC Directives
OMRON devices are designed so that they comply with the related EMC
Directives so that they can be more easily built into other devices or the over-
all machine. The actual products have been checked for conformity to EMC
Directives (see the following note). Whether the products conform to the stan-
dards 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 EMC (Electromagnetic Compatibility) standards are as follows:
EMS (Electromagnetic Susceptibility): EN 61000-6-2
EMI (Electromagnetic Interference): EN 61000-6-4
(Radiated emission: 10-m regulations)
Low Voltage Directive
Always ensure that devices operating at voltages of 50 to 1,000 V AC and 75
to 1,500 V DC meet the required safety standards for EN 61131-2.
