Inspection of the DC link capacitors of the PM modules

After the devices have been non–operational in a no–voltage condition for

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

done, when the devices are switched on they can be damaged.

Date of manufactu-

The production date can be derived from the following assignment to the serial

number (e.g. S T-S9VVVVVVV für 2004, September):

The serial number is stamped on the type plate.

When forming, the DC link capacitors are subject to a defined voltage

and a limited current. This means that the internal relationships requi-

red for the DC link capacitors to function are restored.

It is important that the storage period is calculated from the date of manufacture

and not from the date that the equipment was shipped.
