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 system components such as braking resistors and filters. 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.

0.4 1/2 L100-004MFU2/MFR2
0.75 1 L100-007MFU2/MFR2
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
