currents e.g. in
˜
Wind power systems
˜
Inverters
Mounting Recommendation
Excessive mechanical strain, e.g. pressure
or shock onto the capacitor body, is to be
avoided during mounting and usage of the
capacitors.
Packing
Transportation-safe packing in
cardboard boxes.

Metal contact layer
(schoopage)
Termination
The capacitors are non-polarized and
are optionally available with „male“ and
„female“ terminations. The earth bolt is
electrically inactive and serves for fixing
and/or earthing of the metal case.
Encapsulation:
Aluminium case with PU-sealing, UL 94 V-0
Terminations:
Screw connection (male or female), screw
bolt M12 x 16.
