Forming the DC link capacitors
Description
If the Line Modules and Motor Modules are kept in storage for more than two years, the DC-
link capacitors have to be reformed. If this is not performed, the units could be damaged
when they are switched on.
If the cabinet is commissioned within two years of its date of manufacture, the DC-link
capacitors do not need to be reformed. The date of manufacture can be taken from the serial
number on the rating plate.
Note
The storage period is calculated from the date of manufacture and not from the date that the
equipment was shipped.
