4.8.2 Customer terminal block
4.8.2.1 Customer interface / shield connection
Note
Preassignment and position of the customer terminal block
The factory setting and description of the customer terminal module can be found in the
circuit diagrams.
The location of the customer terminal module in the enclosed drive is indicated in the layout
diagram.
Version without option G65
The TM31 Terminal Module is used in the cabinet units as the customer terminal block; the
external signals must be connected to it.
Version with option G65
For cabinet units with option G65, the connections of the TM31 Terminal Module are routed
to an interface module (-X65 to which customer connections with a larger conductor cross-
section can be made.
Shield connection
The shield connection of shielded control cables on the customer terminal module (-A60 or
-X65) is established in the immediate vicinity of the terminal module. For this purpose, the
customer terminal module –A60 and the mounting plates have cut-out sections which are
used to snap the enclosed 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 enclosed drive because all the
shield connections are identical in design.
