* Only one can be installed in bypass option enclosure. If both are required, a separate enclosed reactor is required.

NOTE:

HA1 option is a bypass package rated to 178 amps at 480 Vac. Though it does not meet NEC for 150 hp of 180 amps, the package will be able to control a high percentage of 150 horsepower motors.

Typical Specifications SED2 Bypass Options shall send the motor to bypass mode based on an easily accessible door-mounted selector or based on the drive’s programmable relay. A bypass pilot light shall provide indication of the bypass mode. The bypass mode shall provide overload protection. Contactors shall be electrically and mechanically interlocked. An essential services mode shall send the motor to bypass regardless of the selected mode.

NOTES:

1. 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, P0748 = Digital Out 1 Reverse ( 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. Refer to Siemens Publication No. 125-3208 for proper fuse and wire sizes. 8. Refer to Siemens Publication No. 125-3201 for SED2 input/output control signal wiring details. Figure 3. Bypass Power Circuit.
