DOK-ECODRV-DKC01/11.1*-PRJ3-EN-P
The mounting plate or the control cabinet housing to which the DKC is
mounted are the preferred locations for assembly.
DANGER
Live parts (greater than 50 V)!
Electric shock on contact!
⇒
Before startup operation, the protective ground con-
ductor must first be permanently connected to the fil-
ter and then grounded!
⇒
Before touching bare connection lines and terminals,
isolate the filter with the connected terminals or dis-
connect it. Allow time for discharging! Do not work on
connecting cables until then!
⇒
Due to the high discharge current of the filter, opera-
tion is not permitted without a connected protective
conductor!
⇒
This is why the filter may only be operated with a per-
manently connected protective conductor with a cross
section
≥
10 mm
2
!
⇒
Remove any paint or coatings from the mounting
points of the filter.
⇒
Use a tooth-lock washer with galvanized or tin-plated
screws.
