Mounting parts
q
If the vibration stress is
≤
5
g
and the capacitors are
≤
60 mm
in diameter and
≤
160 mm in height, the bolt is used for mounting.
q
For capacitors without mounting bolt and in case of a vibration
stress > 5
g
as well as for larger-sized capacitors refer to chapter
“Mounting parts”.
Grounding
q
Mounting bolt or grounding strap
for grounding in accordance with VDE 0100
q
Grounding identification in accordance with DIN 40 011
Overpressure disconnector (mechanical)
When the overpressure disconnector responds,
the capacitor extends by up to 8 mm.
So leave sufficient space above the terminals when mounting the capacitor.
Individual data sheets
Individual capacitors of this series are specified in detail
(incl. thermal data)
on pages 78 … 93.
Upon request, these data sheets are available for each capacitor type.
