Name and description
R (L1)
Power input terminals
A2j: Three-phase 200 to 230 VAC, 50/60 Hz
S (L2/N)
A2
: Three-phase 200 to 230 VAC, 50/60 Hz
ABj: Single-phase 200 to 240 VAC, 50/60 Hz
Three-phase 200 to 230 VAC, 50/60 Hz
T (L3)
A4j: Three-phase 380 to 460 VAC, 50/60 Hz
Note: Single-phase power must be input between terminals R to S.
B1
Braking resistor connection terminals (see note)
B2
Terminals for connecting an optional braking resistor
Note Before shipping, a resin plate is attached to each braking resistor connection ter-
minal to prevent incorrect wiring.
When connecting a braking resistor, always remove the resin plates with a pair of
long-nose pliers.

W
Motor output terminals
Three-phase power output terminals for operating the motor. (Never connect
an AC power supply to these terminals.)
A2j, ABj: Three-phase 200 to 230 VAC
A4j: Three-phase 380 to 460 VAC
Note: Depending on input voltage
Ground terminal
Always use a ground terminal with one of the following ground resistances:
100 Ω or less for 200-VAC class
10 Ω or less for 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.
