SED2 VD NEMA Type 3R Bypass Description The NEMA Type 3R Bypasses are companion packages for the family of SED2 Variable requency Drives. NEMA Type 3R enclosed bypasses are manufactured for outdoor locations that are not in direct sunlight. The 3R rating provides a degree of protection to the enclosed SED2 VD and electrical control components. A heater is supplied to protect against condensation. The standard package is rated to 104 (40 C). A high temperature package, rated to 122 (50 C), is available. The SED2 is designed specifically for HVAC applications and supports a variety of digital and analog I/O and provides built-in PID features to control pumps and fans. or information on the family of SED2 VDs, see the SED2 Variable requency Drives Submittal Sheet (154-042).

SED2 VD NEMA Type 3R Bypass Bypass Control Auto Bypass Relay logic allows user to send the motor to bypass mode based on the drive s programmable relay. Enable Input Generally used for safety tie-ins; the motor will not operate the drive or bypass when open. Common Remote Start/Stop Can be used in both drive and bypass mode. Essential Services Mode Typically used for smoke purge; the motor goes to bypass regardless of the selected mode. No call to stop will have an effect, including open safety or stop commands. Only turning the power off or opening this contact will stop the motor.
