NOTE
• Make sure the power cables are connected to the R/L1, S/L2, and T/L3. However, the FR-CS82S is not equipped with terminal
T/L3. (Phase need not be matched.) Never connect the power cable to the U, V, and W of the inverter. Doing so will damage
the inverter.
• Connect the motor to U, V, and W. (The phases must be matched.)
