6.33.24 Protection against a failure of the control power backup device (optional CPS002Z)


• Function
If the control power backup device (optional CPS002Z) fails to supply power for some reason or other, the
inverter will put out an alarm signal or a trip signal, depending on the setting of this parameter.
Leaving this parameter disabled may cause the main power supply to be turned on and off endlessly if
something unusual occurs, depending on your sequence etc., so you should set this parameter  properly
when using the optional power backup device.
