Conformance to EC Directives 6
• Warm up the Unit for at least 30 minutes to ensure accurate operation.
The indicated temperature error will be larger if the Unit is not warmed up.
• Do not use the Unit in locations where it will be subject to direct radiant
head from a heater.
• Always use round crimp terminals on the AC power terminals of the
Power Supply Unit. Never connect twisted wires to the terminals.
• Do not install the Unit in locations subject to excessive noise. Noise can
cause malfunctions.
• Wire signal lines in separate ducts from high-voltage or power supply
lines.
• Abide by all applicable laws, ordinances, and regulations when disposing
of the Unit.
• Confirm that ratings are correct before replacing any part.

6-1 Applicable Directives
• EMC Directives
• Low Voltage Directive
6-2 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 Applicable EMC (Electromagnetic Compatibility) standards for the CS-series
and CJ-series PLCs are as follows:
EMS (Electromagnetic Susceptibility): EN61000-6-2
EMI (Electromagnetic Interference): EN61000-6-4
(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 CS/CJ-series PLCs comply with EC Directives. To ensure that the
machine or device in which the CS/CJ-series PLC is used complies with EC
Directives, the PLC must be installed as follows:
1,2,3... 1. The CS/CJ-series PLC must be installed within a control panel.
