Conformance to EC Directives 6
• For the Unit power supplies and output power supplies, use power supply
units can will supply a stable output even if the input power is interrupted
for up to 10 ms. The power supply must also have reinforced or double
insulation.
• Do not place any objects on the cables.
• When transporting the Unit, use special packing boxes and protect it from
being exposed to excessive vibration or impact during transportation.

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
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 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 V AC and 75
to 1,500 V DC meet the required safety standards for the PLC (EN61131-2).
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.)
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.
