ZGXM-1B-12K (TY) Signal SPD
Mã sản phẩm : 1490072120
The ZGXM-1B-12K (TY) Signal SPD is connected in series to the input end of protected equipment. Once the transmission line is stricken by lightning strokes and surges, the SPD will shunt the lightning and surge current to the ground, clamping it to an acceptable range of equipment, which protects the equipment (such as the camera, monitor, and mobile telecom).
Features The product is characterized by a fast response speed (ns) and low protection level, small and light. Technical Data

Installation, Usage And Maintenance Installation
1 Before connecting the SPD into the system, first check the grounding resistance of grounding grid, which should meet relevant requirements of specifications.
2 Connect the signal line of system to the input interface at the bottom of SPD, and the output to protected equipment; ensure reliable connections, and do not reverse them.
3 Connect the grounding terminal at the back of SPD to the nearest bus of protected ground, with ground connection as short as possible.
Usage and Maintenance
1 There are the IN and OUT markings on the nameplate of SPD, and do not reverse them;
2 Users cannot disassemble the fastening pieces of SPD at random, in order to avoid damage.
3 If you find that the system does not work properly with the SPD, and can work properly without the SPD, it indicates that there is a problem with the choice of SPD, which should be replaced.
