Table 5-3 EA12 connector- and SU11 terminal assignment
All of the
"ground" terminals
are connected together via 0 Ohm resistors
and are connected to electronics ground via an associated inductance.
5.1.3 Application information and noise immunity
•
operation
without fan
is possible
•
noise-immune operation is only possible if the module is tightly screwed
into the subrack
The input/output signals must be screened on the plant/system side. The
screen must be connected through the largest possible surface area to the
screen rail between the interface module and where the cable enters or exits
the cabinet.
