Overvoltage Protection
The 2N device cables have to be protected against atmospheric overvoltage caused by external causes
(lightning, e.g.). A surge can damage a device installed outside/inside the building if the wires are unprotec-
ted.
Therefore, we recommend that additional overvoltage protectors (OVP) be installed on the outer walls or
roof for all the wires leading outside the building. Keep the following instructions while installing overvoltage
protectors:
