• protect your electric fence unit against overvoltage that can be caused by lightning strikes to the fence system

Installation Instructions please find on page 4 - position 4

To protect against lightning damage, the fence cable on the building must be guided through an overvoltage protection device with throttle and spark gap which is applied to non-flammable material on the outside wall of the building before being connected to the electric fence unit. This also applies to combi-units if they are operated with a mains adapter.
