If the mains failure with or without shutdown takes so long that the frequency in-
verter shuts off completely (LED's = OFF), the frequency inverter will be in the
"Standby" state when the mains supply is restored. If the inverter is released again,
the drive will start. If the drive is to start automatically after restoration of the mains
supply if the inverter is released permanently,
must be switched on.
