The 37-way cable distributor consists of a connector housing (SINUMERIK
version) for a 37-way sub D plug-in connector with enlarged interior. Seven
cable inlets are provided at the rear of the cable distributor to which the cables
have to be connected as shown in Table 4-13.
Push the cables into the open cable distributor to plug-in connectors X1 to X10
and place the cable in the cable inlet. Make sure that the exposed shield jackets
have a large--area conductive connection with the metal contact surfaces as
shown in Fig. 4-5. Insert the upper terminal clip in such a way that its "teeth" are
facing the "teeth" of the lower terminal clip and then fasten the upper housing
member.
As a result, the cable shields are forced in between the contact surfaces of the
contact springs and make contact. By fastening them to the front panel of the
CCU, the shield potential is conducted via the contact springs of the cable
distributor.
