Terminals for connecting an optional braking resistor
Note Before shipping, a resin plate is attached to each braking resistor connection terminal to prevent
incorrect wiring.
When connecting a braking resistor, always remove the resin plates with a pair of long-nose
pliers.

Motor output terminals
Three-phase power output terminals for operating the motor. (Never connect an AC power
supply to these terminals.)
ABj: Three-phase 200 to 230 VAC
A4j: Three-phase 380 to 460 VAC
Note: Depends on the input voltage.
Ground terminal
Always use a grounding terminal with a ground resistance of followings,
100 Ω or less of 200-VAC class
10 Ω or less of 400-VAC class
(Connect also to the power supply neutral to conform to the EC Directives.)
Be sure to connect a grounding line to the FG terminal and also connect directly to the FG
terminal of the motor.
