Table 11.1:1) The setting of Cat. A type should be defined from Isd = Ir × 1.5 to Isd = Ir × 8 for short time; if such short time is defined
as Isd = Ir × 10, the functions operate normally, but when a problem occurs, as Ir × 10, contact a WEG service center or the nearest
customer service. The manufacturer takes no liability for damage resulting from incorrect application of the instructions provided in this
2) The earth leakage function is available with external CT or ZCT.
