Starting the inverter
If the power module receives a startup command when it cannot be started, the startup command will be
kept for 1 minute. If the startup command is not cleared within 1 minute (for example, other faults occur
on the module, or you perform shutdown or rectify faults) and the module can be started, the module
responds to the startup command.
