Specifications
External resistor type (3G3AX-RBU23/-RBU24/-RBU42/-RBU43)
*1 When using a braking resistor (model 3G3AX-RAB/-RBB/-RBC) for a 400-V-class regenerative braking unit,
connect two of the same size braking resistors in series.
Damage may occur to a 400-V-class regenerative braking unit if operated with only one braking resistor con-
nected.
*2 Set up using DIP switch.
