10.6 Forming the DC link capacitors

Forming the DC link capacitors

If the Basic Line Module, Smart Line Module, Active Line Module, and Motor Module have not

been used for more than two years, the DC-link capacitors must be reformed. If this is not

carried out, the units could be damaged when the DC-link voltage is connected under load.

If the cabinet is commissioned within two years of its date of manufacture, the DC-link

capacitors do not need to be re-formed. The date of manufacture can be taken from the serial

number on the rating plate.

Storage period

It is important that the storage period is calculated from the date of manufacture and not

from the date that the equipment was shipped.
