Determining Wire and Fuse Sizes
The maximum motor currents in your application determines the recommended wire
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 component shown in the “
Basic System Description” on page 2–7. The
“Signal Lines” column applies to any wire connecting to the two green 8-position
connectors just inside the front panel half-door.
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 66 ft. (20m).
Note 4: Use 18 AWG / 0.75 mm
2
wire for the alarm signal wire ([AL0], [AL1], [AL2]
terminals).
Note 5: The inverter’s input power wiring must include UL Listed, dual-element,
600V fuses, or UL Listed, inverse-time, 600V circuit breakers.
