Checklist for proper grounding
The fixation of the green-yellow grounding cable is not sufficient to ensure proper grounding of the structure. It
must also be ensured that all metal parts of the structure are connected in a conductive way!
To ensure proper grounding, all metal parts of the system have to be connected in a
conductive way!
Therefore the corner brackets have to be fixed with nippled hammer bolts!
The same applies for the shielding; due to the coating, in addition spring washers have
to be used!
Check the following items. In case the result is negative, corrective measurements have to be taken!
•
At least one of the hammer bolts to fix the corner brackets for connecting the profiles is a nippled hammer
bolt!
•
The connection brackets between two columns are fixed with nippled hammer bolts!
•
The shieldings are fixed with nippled hammer bolts and spring washers.
•
All coated metal parts mounted into the structure apply at least one nippled hammer bolt and a spring
washer (e.g. support tray switch box (OverView cPU67-DL))!
In case no spring washers have been applied, use the spring washers included in the
grounding kit
The following pictures show some of the details to be checked:
All connections between plain metal (e.g. corner brackets) and the profiles have to be
made with nippled hammer bolts ("long" hammer bolts) (see pictures above, first row).
All connections between coated metal (e.g. shielding) and the profiles have to be made
with nippled hammer bolts and spring washers (see pictures above, second row).
If the structure does not comply with these rules, there is no proper grounding!!
