6 Conformance to EC Directives

Applicable Directives

• EMC Directives

• Low Voltage Directive

Concepts

EMC Directives

OMRON supplies electric devices that are used built into other devices or manufacturing equipment. These OMRON products are designed to conform to the related EMC standards (see note) so that the devices or equipment in which they are used can more easily conform to EMC standards.

EMC-related performance of the OMRON devices that conform to EC Directives 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: EN 61131-2

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 (EN 61131-2).

Conformance to EC Directives

CV-series products conform to EC Directives (see note). However, the following precautions must be observed to ensure that the machine or device in which the CV-series PLC is used conforms to EC Directives:

1. The CV-series PLC must be installed within a control panel.

2. You must use reinforced insulation or double insulation for the DC power supplies connected to the power supply terminals on PLCs that take DC power and for the DC power supplies connected to I/O Units. The DC power supply connected to the power supply terminals on PLCs using DC power must have an output hold time of at least 10 ms.

3. CV-series products conforming to EC Directives also conform to EN 61131-2 for EMI. 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 equipment conforms to EC Direc- tives even when using CV-series products that conform to EC Directives.

Note Of the products that appear in this manual, the following products conform to EC Directives.

Precautions Abide by the following precautions when using separate power supplies for the input points.

1, 2, 3... 1. Use shielded twisted-pair cable for external connections.

2. Connect the positive and negative terminals of any unused input points to the shield terminal.

3. Use separate power supplies for input points 1 and 2 whenever possible. In this case, the shield terminal must be shorted to the negative terminal, as shown in the diagrams above. Failure to do so may cause errors of several percent in the output data.

4. If the same power supply must be used for input points 1 and 2, connect the wiring as shown in the diagram below.

The connections shown in the previous diagrams should not be used for a single power supply, because the internal connections of the shield terminals for input points 1 and 2 inside the Unit cause interference between the input points and inaccurate data will result.

Connect as shown in previous diagram (1) for voltage input signals in common mode.

Connect according to one of the following methods when the same power supply is used for input points 1 and 2.

1, 2, 3... 1. Connect shield terminal to signal supply common terminal.
