Required grounding
Only the PDP must be grounded with the office ground as shown in
the figure below. All the other parts (rack, subracks, ...) are grounded
as a result of the physical mounting (physical/electrical connection of
device and rackframe).
NOTE: If isolated return wire is required (e.g. for the USA
domestic market), the U-bracket (connection between return and
ground) has to be removed!

The U-bracket has to be removed, if the return wire is only
grounded at the external battery (BDFB) source (e.g. valid for
the USA domestic market)
Additional grounding
(optional)
Important! The cables mentioned in the procedure below are not part
of the system delivery, but they can be ordered separately.
