Connect each signal connector terminal of screw compression type with one 0.5 to 2.5 mm
(AWG 24 - AWG 14) wire or with two 0.5 to 1.0 mm
Protective conductor terminal must be connected to the cubicle or station protective earthing
system. Electrical codes and standards require that protective earth cables are green/yellow
conductors with a cross section area of at least 2.5 mm
properly connected to the station earthing system. Use a conductor with a core cross section
area of at least 4 mm
