Precautions for installation of surge protector
- Surge protective devices are installed in parallel in the line, and.
- Please do not connect the circuit in reverse or wrong way.
- The closer the surge protector is installed at the front end of the protected equipment, the better the effect is.
- The equipment needs regular inspection and must be replaced immediately after deterioration.
- Remember not to work with live line.
- The grounding must be good and the grounding resistance should not be greater than 4 Ω.
- The front end of surge protector should be equipped with short circuit device to avoid fire caused by short circuit after deterioration of lightning protection device.
