Lightning Protection

The EDAC 700 RTU must be provided with an earth discharge circuit to allow for
lightning and mains surge discharge.
This can be accomplished by connecting a cable with a M3 crimp terminal attached, to
the M3 mounting screw located beside the RJ45 PHONE socket, at the bottom left
corner of the main EDAC 700 PCB. This cable should then be connected back to a
suitable earth point. This would normally be the common earth buzz bar at the
switchboard, or an external earth stake, located beside the building.
