Step-by-Step Basic Installation

Determining Wire and Fuse Sizes

Inverter Mounting

and Installation

 

 

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 connec- tion, and any other component shown in the “Basic System Description” on page 2–5. The “Signal Lines” column applies to any wire connecting to the two green 7 and 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 mm2 wire for the alarm signal wire ([AL0], [AL1], [AL2] terminals).
