<Check>
• Values of current range and/or frequency are not
displayed in red.
• Vector display is identical with the "Correct Vector
Diagram".
• Voltage vectors (U1, U2, U3) and current vectors
(I1, I2, I3) are displayed.
• Displayed active power value (P1, P2, P3) is not
negative.
3. Execute advanced setup if required.
4. Execute QuickSet.
