2.3.1 Overvoltage Protection

Recommendations for Additional Overvoltage Protection Installation

If running:

a) outside a building,

b) on/in an outer wall or roof,

the 2N device wiring may be exposed to atmospheric effects resulting in overvoltage that may

subsequently damage any devices installed outside the building, on its outer wall or roof.

Overvoltage may damage devices connected to these wires and installed inside the building as

well. Therefore, we recommend that additional surge protectors be installed on all the wires

leading outside buildings, on outer walls or roofs, namely:

a) as close as possible to the device installed outside the building or on its outer wall/roof,

b) as close as possible to the point where the wires leave the building.
