For inverter wiring, crimp terminal, and terminal screw tightening torque, refer to the table below. 
• 
Each table shows an example of connecting the standard 3-phase motor with four poles to an 
inverter. 
• 
For the molded case circuit breaker (MCCB), select an appropriate product in consideration of the 
breaking capacity. 
• 
For compliance with the UL standard requirements, be sure to perform wiring according to A-4 
UL/cUL Standards Cautions on page A-9, which includes the use of UL-compliant Class-J fuses. 
• 
Tighten the terminal block screws with the specified torque. Weak tightening may result in a short-cir- 
cuiting accident or fire. Conversely, overtightening these screws may cause damage to the terminal 
block or the inverter.
