Cabinet Grounding
●
Metal components and parts of cabinets are properly connected. A structural
connection area is protected and applied with antioxidants. An area protected
with painting should ensure proper metal surface contact for two connected
components. The DC resistance is within 0.1 ohm between any two connected
metal components. Use a ground cable to connect two metal components
that cannot be directly connected, such as cabinets and cabinet doors. A cable
for connecting these two metal components has a minimum cross-sectional
area of 6 mm

●
A ground bar or main ground point is provided in each cabinet for equipment
grounding. The ground bar does not have to be insulated.
●
The ground terminal should be greater than or equal to M8. A yellow ground
label such as
is attached close to the main ground terminal for
cabinets.
●
Connect equipotential cables to metal components without carrying currents
in the module, such as metal doors and windows, cable trays, and ESD floor
supports. Each equipotential cable has a minimum cross-sectional area of 6
mm
