Procedure 4-2: Ground wiring
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 rack frame).
NOTE1: 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!
NOTE2: To avoid hazard in case of reversed polarity at power connection, it
must be assured, that in the rack and subrack the DC-Return has no
connection to GND!
