FAQs
Installation and compatibility: The ACH580 with E-Clipse bypass fits standard low-voltage systems and supports 1 to 350 hp at 230/460/575 V. It uses UL-listed, NEMA Type 1/12/3R enclosures and includes a door-mounted control panel, making local control straightforward. Ensure correct wiring, verify interlocks, and use the padlockable OFF position during maintenance.
Performance specs to note: The ACH580 covers 1-350 hp with 230/460/575 V supply, enabling scalable control from small fans to large AHUs. It provides electronic motor overload protection to safeguard motors, and includes an integrated bypass starter for rapid service without disconnecting load power. This combination yields predictable start-up, reduced energy waste, and compliance with safety standards in HVAC installations.
Safety suitability: Yes. The ACH580 supports a motor-disconnect option and door interlock with a padlockable OFF position, enhancing lockout/tagout compliance. The integrated electronic overload protection adds an extra layer of equipment protection, while the built-in control panel allows local diagnostics. For critical environments such as data centers or hospital HVAC, the combination of bypass safety and protective features helps meet stringent safety requirements.
Downtime reduction: The E-Clipse bypass allows the drive to be bypassed without removing power to the load, enabling quick service while the system remains operational. The door-mounted control panel provides local status and trouble-shooting without external tools, and the bypass starter simplifies re-commissioning after maintenance. Together, these features minimize outage duration in HVAC plants.
Automation integration: The ACH580 includes serial communications capability and external control connections to enable plant-wide control via PLCs or SCADA systems. This supports remote monitoring, alarms, and coordinated speed control across multiple fans and pumps, improving energy management and system reliability. The drive’s compatibility with ABB control ecosystems also simplifies procurement, maintenance, and future upgrades in large-scale HVAC networks.
