Chapter 5 Main Circuit Terminals MS300 Frame E Figure 5-12 If you install at Ta 50 ° C above environment, use copper wires that have a voltage rating of 600 V and are temperature resistant to 90°C or above. If you install at Ta 50 ° C environment, use copper wires that have a voltage rating of 600 V and are temperature resistant to 75 ° C or 90 ° C. For VFD33AMS23ANSAA and VFD33AMS23ENSAA models: If you install at Ta 40°C above environment, use copper wires that have a voltage rating of 600 V and are temperature resistant to 90°C or above. For VFD49AMS23ANSAA and VFD49AMS23ENSAA models:
If you install at Ta 35°C above environment, use copper wires that have a voltage rating of 600 V and are temperature resistant to 90°C or above. For VFD32AMS43ANSAA, VFD32AMS43ENSAA, and VFD32AMS43AFSAA models: If you install at Ta 45°C above environment, use copper wires that have a voltage rating of 600 V and are temperature resistant to 90°C or above. To be UL installation compliant, you must use copper wires when installing. The wire gauge is based on a temperature resistance of 75 ° C, in accordance with UL requirements and recommendations. Do not reduce the wire gauge when using high-temperature resistant wires. **Wire these drives by ring lugs with specified dimensions.
