11. Technical data
11.1 Ambient conditions
Note:
Please pay attention and consider for the operation of IE3 motors while
dimensioning of dc brakes the resulting higher starting currents.
For the use of IE3 motors we highly recommend to dimension and design
the needed braking devices one size higher.
