u Wire Gauge and Tightening Torque Specifications
Note: 1. For 0 to 100 A, use a minimum of 60 °C - 75 °C copper wire.
2. For above 100 A, use a minimum of 75 °C copper wire.
3. Wire gauge recommendations based on drive continuous current ratings using 75 °C 600 Vac vinyl-sheathed wire assuming ambient
temperature within 40 °C and wiring distance less than 100 m.
• Consider the amount of voltage drop when selecting wire gauges. Increase the wire gauge when the voltage drop is greater
than 2% of motor rated voltage. Ensure the wire gauge is suitable for the terminal block. Use the following formula to
calculate the amount of voltage drop:
Line drop voltage (V) = 3 × wire resistance (Ω/km) × wire length (m) × current (A) × 10

• Refer to UL Standards Compliance on page 439 for information on UL compliance.
