as possible.
Step 2: According to the distance to the grounding screw of the switch, cut the
grounding cable of the arrester, and securely tightening its grounding cable to the
grounding screw of the switch.

with switch by the cables (be carefully with the cable direction. Outdoor network cable
should be inserted into the arrester's IN end, and the cable connected to the switch
