2-2-8 Conforming to EC Directives

Applicable Directives
■
• EMC Directive: EN 61800-3
• Low Voltage Directive: EN 61800-5-1
Concepts
■
● EMC Directive
OMRON products are designed for compliance with related EMC standards so that they can be more
easily built into other devices or the overall machine. The 3G3JE has been checked for conformity to
EN 61800-3 when the following installation and wiring methods are used. EMC-related performance
of the OMRON products that comply with EC Directives will vary depending on the configuration, wir-
ing, installation, and other conditions of the equipment or control panel on which the OMRON prod-
ucts are installed. The customer must, therefore, perform the final check to confirm that devices and
the overall machine conform to EMC standards.
● Wiring the Power Supply
• Always connect the power input terminals (R/L1, S/L2, and T/L3) and power supply via a 3G3JV-
PRS2010J Noise Filter (rated current: 10 A).
• Reduce the length of the ground wire as much as possible.
• Locate the Noise Filter as close as possible to the Inverter.
● Connecting a Motor to the Inverter
• When connecting a motor to the Inverter, be sure to use a cable with a braided shield.
• Reduce the length of the cable as short as possible.
Conforming to the Low Voltage Directive
■
The 3G3JE conforms to EN 61800-5-1 when the following installation and wiring methods are used.
• The 3G3JE is an open-frame device. Always install it in a control panel.
• Always use reinforced or double insulated power supply/voltage (SELV) wiring for the control circuit
terminals.
• The Low Voltage Directive requires that protection from short-circuiting in the power supply wiring
be provided with a molded-case circuit breaker (MCCB). Always install an MCCB on the power sup-
ply side of the Inverter.
• Use one MCCB per Inverter.
• Use an MCCB with the rated current given in the following table.
