(Optional) Installing a lightning arrester for an AC power
module
No lightning arrester is provided with the firewall. Purchase one as needed.
If part of the AC power cord is routed outdoors, install a lightning arrester to the power input end to
protect the firewall from being damaged by lightning strikes. You can attach the lightning arrester for
an AC power module to the rack, workbench, or a wall of the equipment room.
For more information about how to install and maintain a lightning arrester for AC power modules,
see the documents provided with the lightning arrester.
