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.
Connect the signal line of system to the input end of SPD, and output to protected equipment; ensure reliable connections, and do not reverse them.
Connect the grounding terminal of SPD with the nearby bus of protected ground, with the ground connection as short as possible.

Usage and Maintenance
1 There are the IN and OUT markings on the enclosure of SPD, with the output end connected to protected equipment, and do not reverse them; otherwise the SPD will be damaged, and equipment cannot be effectively protected.
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.
