 EMC
OMRON products are the electrical devices incorporated and used in various machines or manu-
facturing equipment. For this reason, OMRON makes efforts to manufacture products that meet the
related EMC standards so that the machines or equipment in which they are incorporated can easi-
ly comply with the EMC standards.
The 3G3M1 Series Inverter complies with EN61800-3 when installed and wired to equipment ac-
cording to the methods described below. However, the customer's machines and equipment vary in
type, and in addition, EMC performance depends on the configuration and electrical characteristics
of mechanical parts, and the configuration, wiring and location of the control panel. This does not
allow OMRON to verify compliance under the customer's usage conditions.
Please perform the final verification on the EMC compliance of your machines or the entire system
at your own responsibility.
 EMC noise filters
OMRON is currently preparing a line up of EMC noise filters.
 Wiring for power supply
Keep the ground cable as short as possible.
Place the inverter and the noise filter on the same earth (ground) plate.
Always connect the power supply input terminals (L1/R, L2/S, L3/T) of the inverter to the power
supply via an EMC noise filter.
Keep the cable between the inverter and the EMC noise filter as short as possible (40 cm maxi-
mum).

 Wiring between inverter and motor
For cables between the inverter and motor, be sure to use shield braided cables.
Keep the cables as short as possible.
