brake is controlled via the brake output.

Hazardous voltage
Danger of death or serious injury
The brake is only switched in a single phase. This means that voltage may be present at
pin 6 even when the system is switched off.
Externally supplied motor brakes are usually powered via a jumper on the motor terminal
board.
Since switching the motor and brake simultaneously can increase wear and tear to the
brake, all M200D motor starters can be fitted with an optional electronic brake controller
(order variant).
