Dynamic brake calls for extra equipment and safety considerations. For further information, please contact Danfoss.

1.

Use cable clamps to connect the shield to the metal cabinet of the adjustable frequency drive and to the decoupling plate of the brake resistor.

2.

Dimension the cross-section of the brake cable to match the brake current.
