Figure 2-3 Typical drive rating label
2.4.1     Output current
The continuous output current ratings given on the rating label are for maximum 40°C (104°F) and 1000m altitude. Derating is required for higher 
ambient temperatures >40°C (104°F) and higher altitude. For derating information, refer to section 12.1.12 Altitude on page 150.
2.4.2     Input current
The input current is affected by the supply voltage, frequency and load inductance. The input current given on the rating label is the typical input 
current.
