FAQs
To install, verify 230 V input and maximum current of 15.7 A, mount the unit in a compliant enclosure, and wire the motor to the drive outputs following the included ABB wiring diagram. Program essential parameters such as acceleration, deceleration, and maximum speed. If BACnet MS/TP is used, configure the communications settings to match the building management system. Perform a post-installation test to confirm smooth ramping and stable operation of the connected pumps and fans.
Yes. The ACS320-03U-10A8-2 is designed for OEM pump and fan applications, supporting up to 2+ HP motors and 230 V supply. Its compact form factor, UL-listed safety, and built-in BACnet MS/TP facilitate OEM integration, reduce external controllers, and enable straightforward retrofit into existing OEM packages. Properly matched to motor load and duty cycle, it delivers reliable control with minimal footprint.
The ACS320-03U-10A8-2 includes embedded BACnet MS/TP, enabling direct communication with building management systems without needing additional controllers. This simplifies commissioning, enhances real-time monitoring, and improves fault reporting for pumps and fans. The result is centralized visibility, better energy management, and faster response to alarms or performance deviations in HVAC networks.
The device provides precise speed control for pumps and fans, enabling variable-speed operation that matches load demand rather than running at fixed speeds. This reduces unnecessary energy use, lowers peak demand, and extends motor life by reducing mechanical stress. When combined with BACnet integration, facilities can implement smarter scheduling and fault-driven maintenance to further optimize energy performance.
The ACS320-03U-10A8-2 is UL-listed for safety with a 2+ HP capability, and ABB typically ships products that meet CE-mark expectations for international markets. This combination supports compliance with major safety and electrical standards while enabling deployment in diverse HVAC installations. Always verify the latest certification status from ABB documentation or the supplier for your region.
