SED2 VD NEMA Type 3R and Type 3R Harsh Environment (3RHE) Bypass Description The NEMA Type 3R Bypasses are companion packages for the family of SED2 Variable requency Drives (VD). NEMA Type 3R/3RHE enclosed bypasses are manufactured for outdoor locations that are not in direct sunlight. Two primary styles of 3R cabinets are provided. The standard 3R rating provides protection from falling rain to the enclosed SED2 VD and electrical control components. The harsh environment 3R rating is identical to the standard, but it is supplied with a more robust NEMA 12 SED2 drive suitable for corrosion and coastal environments. A heater is supplied in the Type 3R models 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). eatures Bypass Power 3-Contactor: Input, Output and Bypass Overload protection in bypass mode. Step-down transformer with fused primary and secondary. Contactors electrically and mechanically interlocked. Drive test function. Complete electrical isolation of drive. Input Device used disconnect. All doors are interlocked and padlockable. Reactor Options Line reactor mounted in bypass enclosure. Line reactor supplied separately (in NEMA Type 3R enclosure). Load reactor (in NEMA Type 3R enclosure) supplied separately. 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. Bypass Door Mounted Control Devices Drive-Off-Bypass selector Bypass pilot light Drive Test On-Off selector

UL, cul Conformity with EC Low Voltage Directive 73/23/EEC SED2 Compliance with EN61000-3-12: rom September 1st, 2005 all electrical apparatus covered by the EMC directive will have to comply with EN61000-3-12 Limits for harmonic currents produced by equipment connected to public low voltage systems with input currents > 16A and =< 75 A per phase. variable speed drives of the product range SED2 (Micromaster 436) fulfill the requirements of the EN 61000-3-12 (without the need for external line reactors) regarding the THD values of Table 3 under the pre condition of Rsce > 190. The required PWHD values will not be achieved. Due to this fact it is recommended to apply for connection approval at the local electricity board. The local electricity board will evaluate among many other data the content of the 5th harmonic current and the Line Power actor "Lambda, which is the ratio of active power and apparent power. frequency inverters are optimized in design and operation characteristics regarding energy efficiency and less interference with line supplies.
