1. Use a double-faced adhesive tape to stick the lightning protector onto
the wireless switch chassis, and make sure it is as close to the grounding
screw of the wireless switch as possible.
2. Measure the distance between the protector and the grounding screw of
the wireless switch, cut the ground wire of the protector as appropriate,
and securely tighten the ground wire to the grounding screw of the
wireless switch.
3. Use the multimeter to measure whether the ground wire of the protector
contacts well with the grounding screw of the chassis.
4. Insert the outdoor network cable into the protector's Surge end, and the
cable connected to the wireless switch into the Protect end, and look at
the indicators on the lightning protector to verify that the connection is
correct.
5. Use nylon ties to bundle the cables neatly.

Precautions
The performance of the port lightning protector may be adversely
affected in the following cases:
• The port lightning protector is installed in reverse direction.
You should connect the Surge end to the outdoor network cable and the
Protect end to the network port on the wireless switch.
• The port lightning protector is not well grounded.
After the connection, you should use the multimeter to confirm that the
ground wire for the protector is as short as possible to ensure its good
contact with the grounding screw of the wireless switch.
