Multi-function Compact Inverter 3G3MX2-EV2 User’s Manual (I666-E1)
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.
