Concepts
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
The applicable EMC (Electromagnetic Compatibility) standard is EN61131-2.
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).

Conformance to EC Directives
The CP1L PLCs comply with EC Directives. To ensure that the machine or
device in which the CP1L PLC is used complies with EC Directives, the PLC
must be installed as follows:
1,2,3...
1.
The CP1L PLC must be installed within a control panel.
2.
You must use reinforced insulation or double insulation for the DC power
supplies used for I/O Units and CPU Units requiring DC power. The output
holding time must be 10 ms minimum for the DC power supply connected
to the power supply terminals on Units requiring DC power.
3.
CP1L PLCs complying with EC Directives also conform to EN61131-2. Ra-
diated 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 equipment complies with EC Directives.

Relay Output Noise Reduction Methods
The CP1L PLCs conforms to the Common Emission Standards (EN61131-2)
of the EMC Directives. However, noise generated by relay output switching
may not satisfy these Standards. In such a case, a noise filter must be con-
nected to the load side or other appropriate countermeasures must be pro-
vided external to the PLC.
Countermeasures taken to satisfy the standards vary depending on the
devices on the load side, wiring, configuration of machines, etc. Following are
examples of countermeasures for reducing the generated noise.
