5.3.1

Description

Capacitor modules are used to increase the DC link capacitance to bridge momentary power
losses.
Capacitor modules are connected to the DC link voltage via the integrated DC link busbars.
Capacitor modules function autonomously.
Several capacitor modules can be operated in parallel.

Safety Information

Warning
After disconnecting all the supply voltages, a hazardous voltage will be present in all
components for another 5 minutes. The protective cover must not be opened until this time
has elapsed.
When opening the protective cover for the DC link, you must activate the release. A suitable
tool (e.g. screwdriver) must be used for this purpose.
The components must only be operated when the protective cover of the DC link is closed.
Damaged components must not be used, otherwise this could result in secondary damage
or accidents.
Caution
The DC link discharge voltage hazard warning must be affixed to the modules in the local
language.
A set of labels in 12 languages is available using order number: 6SL3166-3AB00-0AAx.
Notice
The 80 mm clearances above and below the components must be observed.
Notice
The capacitor module is precharged by the line module. The relevant charging limits of the
line modules must be taken into account.
Caution
The left and right ends of the DC link busbar of a drive line-up must be fitted with peripheral
covers (order no.: 6SL3162-5AA00-0AA0).
