Incoming time of
P1333
input voltage

If the voltage values of input three phases are all lower than voltage threshold of input
power loss(P0484), and MCB is still closed after the delay time (P1332) ， input power loss
fault is generated.

Input Under Voltage
Threshold of input
P0047
under voltage

While MCB is close, if the RMS value of three phase input voltage is lower than
threshold of input under voltage(P0047) in a duration time of P1253, input under voltage
fault is generated.
Table 4-25 Input over voltage
ID Parameter
Fault duration time:
P1254
Input Over Voltage
Threshold of input
P0054
over voltage

While MCB is close, if the RMS value of three phase input voltage is higher than
threshold of input over voltage(P0054) in a duration time of P1254, input over voltage
fault is generated.
