The order numbers for replacement fan fuses can be found in the spare parts list.
Removing fault causes
Make sure that the cause of the fault is found before the fuse is replaced.
8.5 Forming the DC link capacitors
Description
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.
Note
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.
