What can be a reason of drive damage directly after power up?

1. Prospective current is greater that max prospective current declared for ATV. Be sure that prospective current at ATV input is below the value specified in dedicated ATV catalog.. For example max prospective current for ATV630D37N4 is 50kA. 

2. Drive supplied to DC bus. If the drive is supplied to DC bus, be sure that charging current is limited. For small drives (below 18kW for 400V drives) there is precharging ressitor inisde, so current is liited. But drives above 18kW requires either external precharging circuit or charging current to be limited by DC supply.

3. Drive's DC is used to supply other drives to their DC bus. Be sure that other drives, connected to subjected drive will not consume more current than input rectifier of subjected drive can withstand.

4. 
DC bus capacitors needs reforming after long storage, seee dedicated maintenance manual. As an example extract page from ATV630 enclosed.

5. Other reason can be environmental (e.g. conductive dust), overvoltage in the network (lightning) or product wearing (e.g. internal short-circuit, capacitor failure)
