When an AC reduced voltage starter is used, how should the electric brakes be wired for release?

To determine

How the electric brakes be wired for release when an AC reduced voltage starter is used.

Explanation

An electric brake consists of two friction surfaces or shoes that can be made to bear on a wheel on the motor shaft. In a magnetically operated brake, as long as the magnetic coils are energized, the shoes are held in a released position by a magnet. If there is an interrupt in power due to pilot device or power failure, the brake shoes are applied instantly to provide a positive stop.

Refer to Figure 49-2A in the textbook, the terminals of motor are directly connected with the coil leads of an AC magnetic brake (B)...
