4.3.2 Braking resistors (external braking resistors)
If the SK 300E which is to be replaced is not equipped with a braking resistor, in general an internal
brake resistor type SK BR14 must be provided for the SK 2xxE. However, if a braking resistor was
fitted on the SK 300E, for the SK 2xxE a corresponding braking resistor type SK BRE4 must be used
in place of the internal braking resistor SK BRI4.
