Provides an alternate connection for the motor to line power for operation at full speed only, directly from line power.
Three electrically interlocked IEC rated contactors isolate the Drive when operating in Bypass mode. Control logic cir-
cuit provides Hand/Off/Auto functions and safety circuit interlocks. Includes fused 120VAC control transformer, motor
circuit protector/disconnect, motor overload relay, selector switches and indicating lights.
208-240VAC: Stops when main-circuit DC voltage is above 410 V
480VAC: Stops when main-circuit DC voltage is above 820 V
208-240VAC: Stops when main-circuit DC voltage is below 190 V
480VAC: Stops when main-circuit DC voltage is below 380 V
By selecting the momentary power loss method, operation can be continued if power is restored within 2 s
