Determining Wire and Fuse Sizes
The maximum motor currents in your application determines the recommended wore size.
The following table gives the wire size in AWG. The "Power Lines" column applies to the
inverter input power, output wires to the motor, the earth ground connection, and any other
components shown in the "Basic System Description" on page 2-7. The "Signal Lines"
column applies to any wire connecting to the two green connectors just inside the front
cover panel.

Note 1: Field wiring must be made by a UL-Listed and CSA-certified closed-loop terminal
connector sized for the wire gauge involved. Connector must be fixed by using
the crimping tool specified by the connector manufacturer.
Note 2: Be sure to consider the capacity of the circuit breaker to be used.
Note 3: Be sure to use a larger wire gauge if power line length exceeds 66ft. (20m).
Note 4: Use 18 AWG / 0.75mm
terminals).
