NBRA-669C 3ABD5898412 ABB Standard Wiring Method
1. DC Bus Connection: Connect the module’s UDC+ and UDC- terminals to the positive and negative poles of the inverter DC bus correspondingly to realize the power transmission of the braking loop. Ensure the wiring terminals are firmly crimped to avoid virtual connection and poor contact.
2. Braking Resistor Connection: Connect the external matching braking resistor to the special resistor wiring terminals of the NBRA-669C module, forming a complete energy consumption braking loop. Select the resistor model according to the actual braking power demand.
3. Grounding Wiring: Strictly connect the module’s grounding terminal to the equipment protective grounding wire to eliminate static electricity, prevent electrical leakage and improve the anti-interference ability of the whole system.
4. Inspection Before Power-on: After all wiring is completed, check the correctness of line sequence, firmness of wiring and insulation of the circuit. It is forbidden to power on with wrong wiring or short circuit.
5. Debugging Operation: After confirming the wiring is correct, power on the system for idle running test, check the module’s working status, verify the braking function is normal, and then put it into formal load operation.
