Ground terminal Be sure to ground the terminal under the following conditions.
3G3MV-A2j: Ground at a resistance of 100 Ω or less.
3G3MV-ABj: Ground at a resistance of 100 Ω or less.
3G3MV-A4j: Ground at a resistance of 10 Ω or less. To conform
to EC Directives, connect to the neutral point of the power supply.
Note Be sure to connect the ground terminal directly to the
motor frame ground.
Note 1. Connect single-phase input to both the R/L1 terminal and the S/L2 terminal.
Note 2. The maximum voltage at the output side corresponds to the power supply voltage for Inverter
input.
