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 9. 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 / 0.75mm2 wire for the alarm signal wire ([AL0], [AL1], [AL2] terminals).
