Shield support
The shield connection of shielded control cables on the terminal block -X9 is established in
the immediate vicinity of the terminal block. For this purpose, the mounting plates have
cutout sections which are used to snap the supplied shield springs into place. The shields of
incoming and outgoing cables must be applied directly to these shield connections. It is
important here to establish the greatest possible area of contact and a good conductive
connection.
Note
Shield springs
These shield springs can be used for all control cables in the cabinet unit because all the
shield connections are identical in design.
CAUTION
Danger of injury due to cut injuries occurring when the shield is connected
The sharp edges of the shield springs can cause cut injuries.
•
Use the appropriate personnel protection equipment, e.g. gloves.
