The P7/Bypass ac drive provides three-contactor bypass control, permitting motors to be run from either the drive or line current in critical fan, pump, and industrial applications requiring continuous operation. The bypass capabilities allow the motor to be operated from either the P7 drive or directly across the line at full speed. This permits drive maintenance while the motor continues to function.

The drive incorporates its three-contactor bypass arrangement into a UL-listed enclosure. Three electrically interlocked IEC-rated contactors isolate the drive when operating in bypass mode.
