3. Check the AC indicator. If the inverter modules are correctly configured for the input voltage and the switch is
ON, then voltage has been applied to the inverter modules (input contactors are ON). If the indicator does not
light after a few seconds disconnect power and check that each inverter is correctly configured for the input
voltage and all 3 phases are present. Check Status Indicator for any codes that can help. Once it is determined
that input is OK, it is necessary to select and load a process.
