Lenze-AC Tech released the SMVector Frequency Inverter with a highly visible internal disconnect switch on NEMA 4X (IP65) enclosed drives.

Uxbridge, MA – Lenze-AC Tech released the SMVector Frequency Inverter with a highly visible internal disconnect switch on NEMA 4X (IP65) enclosed drives. The switch removes power to facilitate service and maintenance. Use of the disconnect switch in decentralized point-of-use operations, including conveyors, fans, pumps, material handling, stackers, and sorters, results in reduced downtime.
Many electrical codes in North America require a means of power disconnection at the motor, Lenze-AC Tech VFD product manager Steven Dextraze said, “The minimal footprint of the SMVector with Internal Disconnect helps electricians, installers, and OEMs meet those codes with one piece of equipment.”
The Internal Disconnect reduces equipment cost by eliminating the need for a separate external disconnect switch mounted in its own enclosure, and of additional wiring between the disconnect and the drive.
“Drives purchased in NEMA 4X rugged enclosures are usually decentralized, installed close to the motor,” said Dextraze. “Now the user has the means of disconnecting motor power right there
Describing the switch as conforming to European electrical conventions, Dextraze said the addition enhances SMVector drive’s vigilant system protection of voltage monitoring, current monitoring, follower loss management, and over-temperature protection.
