Site conditions before installation
1,There is a reliable grounding system, and the grounding resistance of the distribution cabinet's grounding pile (strip) is measured (SPD installation), and its resistance should meet the national standard.
2,Space should be left in the distribution cabinet for SPD installation.
Note: L is the fire wire, N is the zero wire, E is the ground wire.
Precautions after installation
