The cable distributor (37-pole) consists of connector housing (SINUMERIK ver-
sion) for a 37-pole D-Sub connector with an enlarged interior. The rear contains
seven cable inputs where the cables must be attached as shown in table 4-12.
Plug the cables into connectors X1 to X10 in the opened cable distributors and
route the cable into the cable entry. Make sure that the shield jackets that
became free have a large conductive connection to the metallic contact areas
as shown in figure 4-4. Locate the upper terminal bar in such a way that its
"teeth" are facing the "teeth" of the lower terminal bar and then secure the upper
housing section.
This will reliably press the cable shields between the contact areas of the con-
tact springs and contact them. Fixing to the front panel of the CCU routes the
shield potential via the contact springs of the cable distributor.
