FAQs
Installation requires mounting in a UL Type 1 enclosure, wiring the bypass starter and drive into the same enclosure, and installing an input disconnect switch or circuit breaker with fast-acting fuses. Connect external control signals and configure the door-mounted control panel for local operation. Ensure the system voltage matches 230/460/575 V and the motor is within the 1–75 hp range. This setup minimizes field wiring and accelerates commissioning while maintaining safety.
Yes. The ACH580 supports 230/460/575 V inputs and is rated for 1–75 hp, making it suitable for a broad range of HVAC equipment including fans and pumps in facilities that operate at 575 V. Its integrated bypass and protection features simplify modernization of existing systems and ensure reliable operation across voltage levels.
The ACH580 with E-Clipse bypass features UL certification and a NEMA Type 1 enclosure, providing recognized safety and enclosure protection for indoor installation. It also includes electronic motor overload protection, which supports compliance with standard motor protection practices in industrial environments.
Key safety features include a door interlocked switch that is padlockable in the OFF position, a bypass starter, and fast-acting drive fuses. These elements enable safe maintenance, prevent unauthorized energization, and help meet workplace safety standards while maintaining continuous HVAC operation.
The integrated E-Clipse bypass reduces wiring complexity and field labor during installation and maintenance.
