Installation
The capacitor modules must be installed and cooled according to the regulations given in
the corresponding Instructions.
Ensure careful handling and avoid mechanical stress. Do not bend any components and do
not change the insulation distances during transport and handling. Do not touch any
electronic components and contacts.
Capacitor modules contain electrostatic sensitive devices which can easily be damaged by
inappropriate handling. Do not damage or destroy any electrical components since this
means hazards for your health!
Electrical connection
When working on live capacitor modules, the valid national regulations for the prevention
of accidents (e. g. VBG 4) must be observed.
The electrical installation must be carried out in compliance with the corresponding
regulations (e. g. cable cross-sections, fusing, PE connection). Additional information can
be obtained from the documentation.
The documentation contains notes for EMC-compliant installation (shielding, earthing,
filters and cable routing). These notes must also be observed when using CE-marked
capacitor modules. The manufacturer of the system or machine is responsible for the
compliance with the limit values required by the EMC legislation.
Operation
If necessary, systems including capacitor modules must be equipped with additional
monitoring and protection devices according to the corresponding safety regulations
(e. g. law on technical equipment, regulations for the prevention of accidents). The
capacitor module can be adapted to your application. Please observe the corresponding
information given in the documentation.
After the capacitor module has been disconnected from the supply voltage, live
components and power connectionsmust notbe touchedimmediately becausecapacitors
can be charged. Please observe the corresponding labels on the capacitor module.
All protection covers and doors must be shut during operation.
Note for UL-approved system with integrated capacitor modules:
UL warnings are notes which only apply to UL systems. The documentation contains
special UL-related information.
Maintenance and servicing
The capacitor modules are free of maintenance if the prescribed conditions of operation
are observed.
In operating areas with polluted ambient air, the cooling surfaces of the capacitor module
can get dirty or the cooling openings can block. Under these conditions a regular cleaning
of the cooling surfaces and cooling openings is essential. Do not use sharp or pointed
objects for this purpose!
