Protective and Diagnostic Functions
The 3G3EV has excellent protective and diagnostic functions. The RUN
and ALARM indicators on the front panel indicate the current Inverter sta-
tus, and the data display section also displays information about an error
that has occurred. These functions therefore enable the user to take the
appropriate actions to correct most errors.
