 Minimum resistance of connectable braking resistors
The minimum allowable resistance values of the externally connectable braking resistors are listed in the table
below.
Do not connect braking resistors with smaller resultant resistance than the listed minimum allowable resistance
values.
(For 250kW or greater models, a dynamic braking resistor drive unit (optional separate unit) is needed.)
