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

Installation precautions
The performance of the port lightning protector might be affected in the following cases:
•
The port lightning protector is installed in reverse direction. Connect the IN end to the outdoor
network cable and the OUT end to the network port on the router.
•
The port lightning protector is not well grounded. After the connection, 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 router.
•
The installed port lighting protectors are not sufficient. If the router has more than one network
port connected with other devices through cables outdoor, install a lightning protector for each
network port.
