● This product adopts series connection.
● Please select a product with the same interface type as the protected equipment.
● "IN" of the surge protector is for input, "OUT" is for output. The input terminal is connected to the external line, and the output terminal is connected to the input end of the protected equipment.
● The PE wire of the surge protector must be reliably connected to the grounding wire of the lightning protection system. The connecting wire should be short, thick and straight.
● During the use of the surge protector, regular inspection is required. If any fault occurs, repair or replace it in time to ensure equipment safety.
● Grounding resistance shall not exceed 4Ω.
● Do not disassemble by non-professionals.
