Input Voltage Tolerances

Table 5.3 lists the input voltage tolerances for the three-phase 9960. Transient voltage
conditions must not exceed +15-18% of nominal and must return to a steady-state tolerance
within of +6 to -8% of the normal related voltage in 0.5 seconds or less. Line-to-line
imbalance voltage must not exceed 2.5%. Nonoperating harmonic contents must not exceed
5%.
