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
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
