21. Pin Assignments
To stay in compliance with regulations regarding electromagnetic compat-
ibility it is recommended to use only shielded cables, as optionally avail-
able from Emerson Process Management or equivalent. Customer has to
take care that the shield is connected in proper way. Shield and signal con-
nector enclosure need to be conductively connected, submin-d plugs and
sockets must be screwed to the analyzer.
Using external submin-d-to-terminal adaptor elements (option) affects elec-
tromagnetic compatibility. In this case the customer has to take measures
to stayin compliance and has to declare conformity, when required by leg-
islation (e.g. European EMC Directive).
Adaptor terminals are one-to-one connected to the submin-d pin of same
designation: Terminal 1 is connected to pin 1, terminal 2 to pin 2 etc. !
