An MX2 Inverter that supports the 3G3AX-MX2-MRT-E Option Board can be
recognised from the Inverter type label. Please check that your Inverter type
label displays revision characters in the bottom right corner where the

If these characters are absent, your Inverter does not support the
3G3AX-MX2-MRT-E, so please contact your local OMRON representative.
