Terminals for attaching an external Braking Resistor or
a Braking Resistor Unit. (Connect to detect overvoltage
during braking.)
Connect the DC reactor for suppressing harmonics to
terminals +1 and +2.
When driving the Inverter with DC power, input the DC 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 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
