7.1 Motors with a 230 V AC brake
A 230 V AC brake must be connected to the 4/T2 terminals and the star point of the motor. The current for braking is taken
from one phase and the neutral conductor, see figure 27, which is valid for the following types:
• DOL- types
• ROL- types
• R- type
The motor current monitoring must be increased by the brake value (nominal value of the brake). This has to be set at the
electronic compact starter. For setting the nominal current, please refer to chapter 3.3.
