Overvoltage protection

It is a good idea to protect 2N NETSTAR equipment against the effects of atmospheric overvoltage, although the device itself already contains a certain degree of active overvoltage protection. Protection is made for:

power supply parts in the form of installing active overvoltage protection to the network cable (e.g. 2N POWER PROTECTOR, 2N SAFE)
telecommunication carrier lines (in the form of strengthening the internal protection on individual 2N NETSTAR modules)
on GSM conductors from external antennas (using special connectors with a protection element)

In order to ensure the correct functioning of internal and external 2N NETSTAR overvoltage protectors, it is necessary to perform perfect electrical grounding of the case.
