DIP switch
The 4-pin DIP switch is located at the top of the Braking Module and sets the braking resistor
being used, the cooling method, and the line voltage.
Make the required settings before the Braking Module is mounted in the control cabinet;
once the module is mounted, the DIP switch can no longer be accessed from the front.
