2.3 Connecting to Protective Grounding Line
Proper connection of protective grounding line is important for lightning protection and anti-interference. Proper
connection is as follows:
2.3.1 With Grounding Bar
Connect the yellow-green protective grounding cable to binding post on the grounding bar and fix the screws.
(1) AC power input
(2) Grounding terminal connection
(3) Grounding cable protection
Note:
Firefighting hoses and building lightning rods are not proper options for grounding bar. The grounding cable on the
switch should be connected to the grounding bar in the IT room.
2.3.2 Without Grounding Bar
1) With mud land nearby and allowed to bury grounding bar
Bury an angle iron or steel pipe (≥0.5m) into the mud land. The yellow-green protective grounding cable should be
welded to the angle iron or steel pipe and the welding point should be embalmed.
2) Not allowed to bury grounding bar
If the device supports AC power supply, you can connect it to the grounding bar through the PE line of the AC
power and ensure the PE line in the switchgear room or beside the AC power supply transformer is well-grounded.
