Precautions for installation of surge protector
1. Surge protective devices are installed in parallel in the line.
2. Please do not connect the circuit in reverse or wrong way.
3. The closer the surge protector is installed at the front end of the protected equipment, the better the effect is.
4. The equipment needs regular inspection and must be replaced immediately after deterioration.
5. Remember not to work with live line.
6. The grounding must be good and the grounding resistance should not be greater than 4 Ω.
7. 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.
