FAQs
The ABB ACH580 with E-Clipse bypass is a configurable HVAC drive that combines a variable frequency drive with a bypass motor starter in a compact enclosure. It is designed for commercial and industrial HVAC systems, enabling seamless bypass operation for maintenance while keeping motor control active. It reduces panel wiring, simplifies service, and improves reliability in fans and pumps.
Power the drive with 230/460/575 V on the L1/L2/L3 inputs, connect the motor leads to the drive output, and install the input disconnect or circuit breaker with a door-mounted interlock. Use the local control panel for setup, and connect external control signals and serial communications as required for integration with a PLC or BMS.
Yes. The ACH580 is designed to operate within UL-listed enclosures that meet NEMA Type 1, 12, or 3R standards. This enables safe, compliant installations in mechanical rooms and exposed environments, while maintaining access to a door-mounted control panel for local operation.
The integrated E-Clipse bypass reduces wiring complexity, panel space, and potential fault points. It allows maintenance while the motor remains at least partially powered, decreasing downtime. Over the system lifecycle, you gain faster troubleshooting, lower preventive-maintenance costs, and improved asset availability, which translates to a favorable total cost of ownership for HVAC drives.
Absolutely. The ACH580 provides external control connections and serial communications, enabling seamless integration with PLCs and building management systems. This supports remote parameter updates, fault diagnostics, and centralized monitoring, delivering faster commissioning and improved visibility across distributed HVAC networks.
