2.1. Ground Screw
The industrial Ethernet switch has a grounding screw. After crimping one
end of the grounding wire with the cold-pressed terminal, the grounding screw
is used to fix it at the grounding hole of the chassis. The other end of the
ground wire is reliably connected to the earth. The cross section of the
grounding wire shall not be less than 2.5mm²
2.2. Power Input Interface
The DC power supply models of this series of switches support DC12-48V
power supply by default, and users can choose DC48V to support dual power
input, and the two power supplies are mutually backup.
The AC power supply models of this series of switches support
DC110-370V and AC85-264V power supply. When using AC models, the
voltage can only be input from V1+ and V1-. V1+ connects to live wire L and
V1- to neutral wire N. Connect V2+ and V2-, and pay attention to safety to
