Reader's note
Selecting the power rating for UI modules, refer to Chapter 6.7.5.
For the 28 kW UI, the pulsed resistors must be separately ordered and external-
ly mounted.
For higher regenerative feedback powers, a separate braking resistor module
must be provided or the regenerative power reduced by using longer braking
times.
