Capacitor Module

11.2.1

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.
11.2.2

Safety Information

Risk of electric shock. A hazardous voltage is present for up to 5 minutes after the power
supply has been switched-off.
It is only permissible to open the protective cover after this time has expired.
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 further, as this could result in secondary damage
or accidents.
The DC link discharge voltage hazard warning in the local language must be attached to all
of the components.
A set of labels in 16 languages is supplied with the component.
A ventilation clearance of 80 mm above and below the components must be observed.
NOTICE
The capacitor module is precharged by the line module. The applicable maximum
permissible DC link capacitances of the Line Modules must be taken into account.
