If a unit has been non-operational for more than one year, the DC link
capacitors have to be newly formed. If this is not carried out, the unit
can be damaged when the line voltage is powered up.
If the unit was started-up within one year after having been
manufactured, the DC link capacitors do not have to be re-formed. The
date of manufacture of the unit can be read from the serial number.
