5-1 Wiring
When installing CAT3-DC-MIL, it is a good practice to use shielded
cables for all input and output signals. The shield should be connected
to the earth ground lug on the CAT3-DC-MIL. The shield on the
opposite end of the cable should be left open.
This wiring practice is mandatory in order to comply with the
requirements for Electromagnetic Compatibility, as per EMC-Directive
89/336/EEC of the Council of European Community.
