Installation Procedures

Follow these steps to install a port lightning arrester:
Step1 Use a double-faced adhesive tape to stick the port lightning arrester to the firewall. The port lightning
arrester should be as close to the grounding screw as possible.
Step2 Cut short the grounding cable of the port lightning arrester according to its distance to the grounding
screw. Fix the grounding cable to the grounding screw of the firewall.
Step3 Use a multimeter to check the connection between the grounding cable of the port lightning arrester and
the grounding screw of the chassis.
Step4 Follow the instructions to connect the port lightning arrester with a transit cable. Note that the external
cable should be connected to the IN end while the transit cable should be connected to the OUT end.
Verify that the ACU LED is normal.
Read the instructions of the port lightning arrester carefully before installation.
