Grounding the firewall
WARNING!
•
Correctly connecting the firewall grounding cable is crucial to lightning protection and EMI
protection.
•
Do not connect the firewall grounding cable to a fire main or lightning rod.
If you mount the firewall on a wall, connect the firewall to the grounding facility of the building. For
other installation methods, you can ground the firewall in one of the following ways, depending on the
grounding conditions available at the installation site.
Grounding the firewall with a grounding strip
If a grounding strip is available at the installation site, connect the grounding cable through the
grounding strip.
To connect the grounding cable:
1.
Remove the grounding screw from the firewall chassis.
2.
Attach the grounding screw to the ring terminal of the grounding cable.
3.
Use a Phillips screwdriver to fasten the grounding screw into the grounding hole on the firewall.
4.
Remove the hex nut from the grounding strip.
5.
Use needle-nose pliers to bend a hook at the other end of the grounding cable. Attach the hook
to the grounding point, and secure the hook with a screw.
