Wiring Instructions
NOTE
1. Always connect the power supply for the main circuit
inputs to the power input terminals R/L1, S/L2, and T/L3
(R/L1, S/L2 for single-phase power) via a molded-case
circuit breaker (MCCB) or a fuse. Never connect the
power supply to terminals U/T1, V/T2, W/T3, B1, B2, −,
+1, or +2. The Inverter may be damaged.
For single-phase Inverters, always use terminals R/L1 and
S/L2. Never connect terminal T/L3. Fuses must be of ULclass RK5 fuse or an equivalent.
Refer to page 231 for recommended peripheral devices.
