Ground terminal Be sure to ground the terminal under the following conditions.
3G3JV-A2j: Ground at a resistance of 100 Ω or less.
3G3JV-ABj: Ground at a resistance of 100 Ω or less.
3G3JV-A4j: Ground at a resistance of 10 Ω or less, and connect
to the power supply’s neutral phase to conform to EC Directives.
Note Be sure to connect the ground terminal directly to the
motor frame ground.
Note The maximum output voltage corresponds to the power supply input voltage of the Inverter.
