cables at all. If it uses normal rack, it should remove the paint at the corresponding
grounding point.
Rack Grounding:
If there is a grounding metal frame outside the rack, for example, the metal angle steel
frame at the bottom of the container, the fix hole of the fix frame can be fixed directly
with the metal frame of the container. Then through the grounding of the container to
ensure reliable grounding.

the frame base. Grounding cable must ≥10AWG.
