How do I fix an F5 Charge Switch Protection code for a DG1 drive?

The charge switch fault is a hardware function, there is a soft-start circuit in the drive to make sure the hardware circuit is working correctly when power is on. If the soft-start circuit is not working based off the formula Vinput x 1.414 +100 >Vdclink the charge switch fault will become active. When dealing with this fault it would be go to verify the input voltage levels line to line for each line, all should be equal. From there check the DC bus voltage with a meter to verify voltage level, based off input voltage read it should be 1.414 times that value. If it is high then there is an issue internally with the power or input rectifiers and static checks for the input rectifiers to the DC bus should be performed.
