Ground terminal Be sure to ground the terminal under the following
conditions.
3G3MV-A2j: Ground at a resistance of 100 W or less.
3G3MV-ABj: Ground at a resistance of 100 W or less.
3G3MV-A4j: Ground at a resistance of 10 W 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 theoutputsidecorresponds to the powersupply volt-
age for Inverter input.
