or with a protective conductor with enough crosssection. Make a con-
nection from one of the devices to the PE rail (main earth) in the cabi-
net.As the leakage current >3.5 mA, the following applies to the PE con-
nection: Use protective conductors with the same crosssection as the
mains cables. If the crosssection of the mains cable is ≤10 mm² the PE
connections are to be doubled, or a copper cable with a minimum cross-
section 10 mm

is to be laid.
2) Also connect the PE-conductor terminals of all other components, such
as main filters etc. in a star configuration with the PE bar (main earth) in
the cabinet.
These further components are only required for the D3-DP 3xx/x supply
module.
Information
Material of the cooler or cold plate: aluminium with high conductive trans-
parent passivation.
