P7-40
Output phase lack protection
0: Forbidden
1: Allowed
Choose whether to protect the output phase lack. If 0 is selected, the fault will not be reported when the actual
output phase lack occurs. At this time, the actual current is larger than the current displayed on the panel. There
is a risk. Please use it cautiously.
