Concept of Conformity
EMC Directive
OMRON products are the electrical devices incorporated and used in various machines or
manufacturing equipment. For this reason, we make efforts to conform our products to their related
EMC standards so that the machines or equipment which have incorporated our products should
easily conform to the EMC standards. The 3G3MX models have conformed to the EMC directive
EN 61800-3 by following the installation and wiring method as shown below. Your machines or
equipment, however, vary in type, and in addition, EMC performance depends on the configuration,
wiring, or location of the devices or control panels which incorporate the EC directive conforming
products. This in turn does not allow us to confirm the condition and the conformity in which our
products are used. Therefore, we appreciate confirmation of the final EMC conformity for the whole
machine or equipment on your own.
Wiring the Power Supply
•Be sure to connect the power input terminals (R/L1, S/L2, and T/L3) and power supply via an EMC
conforming dedicated noise filter 3G3AX-EFI
•Keep the ground cable as short as possible.
•Keep the cable between the Inverter and the noise filter as short as possible.
Connecting a Motor to the Inverter
•When connecting a motor to the Inverter, be sure to use shield braided cables.
•Keep the cables as short as possible.
Low-voltage Directive
The 3G3MX models have conformed to the EMC directive EN61800-5-1 by performing the machine
installation and wiring as shown below.
•The 3G3MX models are an open type device. Be sure to install it inside the control panel.
•The power supply and voltage (SELV) with reinforced or double insulation should be used for
wiring to the control circuit terminals.
•To satisfy requirements of the LVD (low-voltage) directive, the Inverter must be protected with a
molded case circuit breaker (MCCB) in case a short-circuiting accident occurs. Be sure to install a
molded case circuit breaker (MCCB) on the power supply side of the Inverter.
•Use one molded case circuit breaker (MCCB) per Inverter.
•Use the crimp-type terminal with an insulation sleeve to connect to the main circuit terminals.
•When not using the braking resistor or braking resistor unit, connect the crimp-type terminal with
an insulation sleeve to the braking resistor connection terminals (P/+2, N/-).
