Main Circuit Connection Diagram

Refer to diagrams in this section for the Main Circuit wiring connections. Connections may vary based on drive capacity.
The main circuit DC power supply powers the control circuit.
NOTICE: Do not use the negative DC bus terminal "-" as a ground terminal. This terminal is at high voltage DC potential. Improper
wiring connections could result in damage to the drive.

◆ Single-Phase 200 V Class (CIMR-TCBV0001 to 0012)
