Installing a 3-Phase Line Monitor Yaskawa requires installation of a 3-Phase line monitor to protect the drive in the event of an input line phase loss. The 3-Phase line monitor must be installed on the primary circuit of the 6-Phase/12-Pulse transformer and connected to the A1000 drive to remove the RUN command when a phase loss condition occurs.
Note: DC power supply input is not available for 6-Phase/12-Pulse Input models. Main Circuit Fuses The A1000 6-Phase/12-Pulse drive requires fuses to be installed on each of the 6 input phases between the 6-Phase/12- Pulse transformer and the A1000 drive. To maintain standards compliance select fuses from Table C.1.
• Use terminal +3 and the negative terminal when connecting a braking unit option. • Do not connect the regenerative converter or the regenerative unit to the 6-Phase/12-Pulse A1000 drive. • Refer to UL Standards Compliance on page 64 for information on UL compliance.
