Energy isolation - shock proof
In rain and snow weather, the air and ground are wet, and the insulation performance will decrease accordingly. Leakage of equipment, power supply and power cord will cause the danger of electric shock.
Before each power transmission, carefully check whether there is water in the equipment and whether the power cord is damaged. Power transmission is strictly prohibited before the water is cleaned up.
Open and close the electric box to keep normally closed state, waterproof measures should be taken when necessary, to avoid water, moisture, short circuit, damage to equipment.
Equipment and tools (electric) should be put away properly after use and placed away from rain and snow to prevent accelerated aging of insulation.
