Installation & Application（安装应用） NKP-TEL-5C-3 Triple Protection Surge Arrester for Network Cameras integrates surge protection for network video signals, control signals, and AC/DC power supply into a single unit, representing a new generation multifunctional surge protection solution for camera devices, surveillance systems and video equipment.
The input terminal of NKP-TEL-5C-3 arrester should connect to external wiring susceptible to lightning induction, while the output terminal connects to protected equipment. Installation requires:
Reliable grounding to provide effective discharge path
Separation from building's lightning protection grounding system to prevent ground potential counterattack
Precautions for Surge Protector Installation
1、The surge protector is connected in series between the protected equipment and the signal channel.
2、The input terminal (IN) of the surge protector should be connected to the signal channel, while the output terminal (OUT) should be connected to the protected equipment and installed as close as possible to it. The connections must not be reversed.
3、Securely connect the surge protector’s grounding wire to the lightning protection system’s grounding bar. The grounding wire should be as short as possible and must not exceed 1 meter in length.
4、This product does not require special maintenance. However, regular inspections of the surge protector should be conducted, especially before and during the thunderstorm season.
5、If a system malfunction is suspected to be caused by the surge protector, first check the corresponding failure indicator light. Alternatively, bypass the surge protector and reconnect the system. If the indicator light does not illuminate or the system returns to normal after removing the surge protector, it indicates that the surge protector is damaged and must be repaired or replaced immediately.
