SED2 Variable Frequency Drives Conventional Bypass (C-Bypass) Options

Submittal Sheet SED2 Variable Frequency Drives Conventional Bypass (C-Bypass) Options Description The Bypass Options are companion packages for the family of SED2 Variable Frequency Drives. For information on the family of SED2 VFDs, see the SED2 Variable Frequency Drives Submittal Sheet (154-042). Bypass Power Features 2-Contactor: Output & Bypass Overload protection in bypass mode. Step-down transformer with fused primary and secondary. Contactors electrically and mechanically interlocked. 3-Contactor (optional): Input, Output, & Bypass In addition to the 2-contactor features, 3-Contactor features provide: Drive test function Complete electrical isolation of drive Input Device Disconnect Input Device Fused disconnect (optional) Drive Drive Circuit breaker (optional) All doors are interlocked and padlockable Motor 2 Contactor Bypass Motor Reactor Options Line reactor mounted in bypass option enclosure. Line reactor (in NEMA 1 enclosure) supplied separately. VF0302R1 3 Contactor Bypass Load reactor mounted in bypass option enclosure. Load reactor (in NEMA 1 enclosure) supplied separately. Input Device Bypass Control Features Auto Bypass Relay logic allows user to send the motor to bypass mode based on the drive s programmable relay. The drive s programmable relay, typically set to fault, can be set up for applications that run full speed for an extended period of time. Enable Input Generally used for safety tie-ins; the motor will not operate the drive or bypass when open. Common Remote Start/Stop 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.

Branch circuit protection to be provided by installer, per UL508A, if not provided with drive. 2. For bypass operation, modify these drive parameters: P0704[0] and P0704[1] = 3. 3. Control and communication wiring should be 300V UL minimum. 4. Communication wiring should be run with maximum separation possible from all other wiring. 5. Essential service mode operates the motor full speed (bypass) with no protection for the motor or system. 6. Ensure that automatic bypass will not damage the system before activating. 7. See Siemens Publication No. 125-3215 for proper fuse and wire sizes. 8. See Siemens Publication No. 125-3201 for SED2 VFD input/output control signal wiring details. Figure 3. C-Bypass Power Circuit.

UL, cul, CE, C-tick Conformity with EC Low Voltage Directive 73/23/EEC SED2 Compliance with EN61000-3-12: Beginning September 1, 2005 all electrical apparatus covered by the EMC directive must 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. Siemens 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 Factor "Lambda, which is the ratio of active power and apparent power. Siemens frequency inverters are optimized in design and operation characteristics regarding energy efficiency and less interference with line supplies.
