3.7 Wiring

When installing CAT3, 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. The shield on the opposite end of the
cable should be left open. Connections are made to the CAT3 terminal
blocks using wire gauges 16 to 28 AWG and 12 to 26 AWG (AC
Power), tightening Torque 0.22 to 0.25Nm.
This wiring practice is mandatory in order to comply with the
requirements for Electromagnetic Compatibility, as per EMC-Directive
2014/30/EU of the Council of European Community.
