3.11 EMC Measures
The 4 Z screws which can be seen in the A3 form connect the internal 0 V potential to
the PE cabinet earth.
If an operation with an isolated processing core becomes necessary due to malfunc-
tions, these screws are to be removed (factory delivery: screwed in).
A capacitive connection to PE is also possible in this case if the potential rail desig-
nated with “0 V” (slot 0612) is connected to “PE” via 1 MOhm / 4.7 μF-400 V - as de-
scribed in part 40, configuration, page 40-31-03.
The reference potentials of M1 and M4 are to be earthed capacitively with isolated in-
puts/outputs and especially with semi-conductor outputs: 0.1 μF / 400 V is sufficient.
3.12 Documentation
DIN A3 form sheets are available for the (Ruplan) processing for the project-specific
documentation. Forced or standard settings of circuit elements are already entered
here. These form sheets are included in the form block
for conventional processing and in the A500 data bank
(see ordering data)
for Ruplan processing (TVN version)
(in preparation)
