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.

Terminals for attaching an external Braking Resistor or a Braking
i l Resistor Unit. (Connect to detect overvoltage during braking.) R i U i (C
Connect the DC reactor for suppressing harmonics to terminals +1
and +2.
When driving the Inverter with DC power, input the DC power to
terminals +1 and –.
(Terminal +1 is a positive terminal.) (Terminal +1 is a positive 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.
