Description
The ABB RINT-5611C (Part Number 68718929) is a Main Circuit Interface Board designed for use within the ABB ACS800 series variable frequency drives. It is specifically engineered for ACS800-01 and ACS800-04 units with an R6 frame size, operating on 380–500 VAC supply systems. This board serves as a critical interface between the drive's control electronics and the power section, facilitating signal processing, communication, status monitoring, and coordination of drive operations.
Features
- Serves as the primary interface for conditioning, isolating, and transmitting signals between the main power circuit and control/protection systems.
- Provides robust galvanic isolation between high-power primary circuits and sensitive low-voltage electronics to ensure measurement accuracy and system safety.
- Integral component for fault management and stable drive performance.
- Compatible with ACS800 R6 frame configurations.
Applications
- Mining and Metallurgy: Hoists, conveyor belts, crushers, and steel rolling machinery.
- Petroleum and Chemicals: Drilling pumps, injection pumps, centrifuges, and large-scale fans.
- Electric Power Industry: Coal feeders, induced draft fans, and circulating water pump systems.
- Shipbuilding: Propulsion systems and deck machinery including winches and cranes.
- Papermaking and Water Treatment: Multi-drive control systems and large-scale pumping stations.

Installation Guidelines
- Qualified Personnel: Only licensed electricians should perform installation and maintenance.
- Power Isolation: Isolate all main and auxiliary power supplies. Perform proper Lock-Out/Tag-Out (LOTO) procedures.
- Capacitor Discharge: Wait at least 5 minutes after shutting off input power to allow intermediate circuit capacitors to discharge.
- Voltage Verification: Measure voltage between terminals UDC+ and UDC-, and across phases U1, V1, W1, to ensure the potential is near 0 V before handling components.
- Maintenance Note: The replacement kit includes an internal cooling fan (PN: 63998931); this fan must be replaced simultaneously with the RINT board to ensure proper thermal management.
