Selecting "current monitoring" o r "power monitoring"
Note that a current not more than 5% of the rated current of the inverter cannot be detected and
displayed.
Also note that the electronic thermal relay does not operate at that current. For motor protection,
examine the use of an external temperature detector or the like.
Example: When a small motor (0.4kW motor) is run by a large-capacity inverter (55kW), power
monitoring is inactive.
