Wire Sizes
The maximum motor currents in the application determine the recommended
wire size. The following table gives the wire size in AWG. The Power/Motor
column applies to the inverter input power, output wires to the motor, the ground
connection, and any other component shown in the system wiring diagram. The
“Signal Lines” column applies to any wire connecting to the External I/O
Connection inside the bottom front panel half-door.
Table 4-1: Wire Size
Note 1: Field wiring must be made by a UL-listed and CSA-certified closed-loop
terminal connector sized for the wire gauge involved.
Note 2: Be sure to consider the capacity of the circuit breaker to be used.
Note 3: Be sure to use larger wires for the power lines in the distance exceeds 20
meters.
