Installation & Application（安装应用） NKP-TEL-5C-2a Compact Dual-Combo Surge Protector for IP Cameras
This next-generation hybrid SPD integrates both network video signal and AC/DC power surge protection into a single compact unit, specifically designed for surveillance cameras and video equipment systems.
Key Installation Notes:
Excludes control line protection
Input terminal must connect to lightning-exposed wiring
Output terminal connects to protected equipment
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.
