Section 1 General Information Introduction The Baldor digital three phase multipurpose soft–starter provides reduced voltage, three phase motor starting and control over the four periods of motor operation. First, at “Start–up” (soft–start), the motor starting voltage increases from an initial preset level to full motor voltage to provide smooth motor acceleration to full speed. Second, the “Dwell” period begins when maximum motor voltage is achieved. This dwell period allows time for the mot

AC Main Circuit Power Disconnect A power disconnect should be installed between the input power service and the control for a fail safe method to disconnect power. Protective Devices Recommended fuse sizes are based on the following: 175% of maximum continuous current for time delay. 300% of maximum continuous current for Fast or Very Fast action. Note: These general size recommendations do not consider harmonic currents or ambient temperatures greater than 40°C. Be sure a suitable input power p

NEMA 12/4 Installation When a NEMA12, NEMA4, NEMA4x OR IP65 enclosure is used, a separate Top of Ramp Bypass (or shunt) contactor must be connected in parallel with the soft–start control. This will allow a solid connection of the motor to the AC power lines and eliminate the heating effect caused by the SCR’s. At the completion of the start ramp (when full start voltage is obtained) a Bypass contactor is closed. This contactor is controlled by the “Top of Ramp” relay K2. This ensures that
