8.2 DEFINITIONS OF DERATING FACTORS
8.2.1 Introduction
This item of the manual deals with the derating that should be considered when sizing the inverter. In cases where
more than one condition require the output current derating, the factors must be multiplied according to the equation
below:
Table 8.8: Current, power and loss data for T4 line and "HD" overload class
HD overload class:
150% for 60 seconds with a 5-minute interval
200% for 3 seconds with a 5-minute interval
