EC Directives 6
• Double-check all the wiring before turning ON the power supply. Incorrect
wiring may result in burning.
• Tighten the PLC Backplane mounting screws, terminal block screws, and
cable (connector) screws to the torque specified in user manuals.
• Confirm that no adverse effect will occur in the system before attempting
any of the following:
• Changing the operating mode of the PLC
• Force-setting/force-resetting of any contact in memory
• Changing the present value or any set value in memory
6 EC Directives
CS-series products confirm to EC Directives. For the system to conform to EC
Directives, however, the following precautions must be adhered to.
• CS-series Units must be installed within control panel.
• Use reinforced insulation of double insulation for the DC power supplies
used for the I/O power supplies.
• CS-series products that meet EC Directives also meet the Common
Emission Standard (EN61000-6-4). The measure necessary to ensure
that standards, such as the radiated emission standard (10 m), are met,
however, will vary depending on the overall configuration of the control
panel, the other devices to the control panel, and wiring. You must there-
fore confirm that EC Directives are met for the overall machine or device.

EMC and Low Voltage Directives
EMC Directive
In order that OMRON products can be used with any machinery and in combi-
nation with other manufacturer's equipment, the products themselves are
designed to comply with EMC standards (see Note), so that the assembled
machinery or device can then also easily comply with EMC standards.
Even if machinery and equipment complies with EMC standards before
assembly, this compliance may change depending on the device, the configu-
ration of the control panel, and wiring, so OMRON cannot guarantee that a
particular system complies with the directive. You must therefore confirm that
EMC Directives are met for the overall machine or device.

EMS: Electro-Magnetic Susceptibility standard EN6100-6-2
EMI: Electro-Magnetic Interference standard EN61000-6-4
