3.2.1.7 Dynamic Brake Connections
For NEMA 1 and NEMA 4X Drives rated up to 25 HP the Dynamic Brake connections are made as illustrated herein.
Refer to the SM2 and SM4 Dynamic Brake instructions for complete information.
NEMA 1 (IP31) up to 30 HP
NEMA 4 (IP65) up to 10 HP
The 40...40HP (30...45kW) models include a dynamic brake transitor as standard and only require the connection
of an external resistor kit for dynamic braking operation. The dynamic brake resistor connections for 40...60HP
(30...45kW) drives are standard built-in connections as illustrated in the diagram below. In the 40HP (30kW) model
drives, the dynamic brake connector is on the right-hand side of the drive and the terminals from top to bottom are
B-, BRAKE and B+. In the 50/60HP (37.5/45kW) model drives, the dynamic brake connector is on the left-hand side
of the drive and the terminals from top to bottom are B+, BRAKE and B-.
