Operation in combination with the self power management function for the separated
converter type
When the self power management function is used with the separated converter type, the input sig-
nal operations are as follows.
When Pr. 138="0 (electronic bypass invalid at a fault)", MC2 is OFF. When Pr. 138 = "1 (electronic
bypass valid at a fault)", MC2 is ON.
The self power management operation is effective.
