What do you mean by L and N in the power supply?
L line of fire with the line to understand the road N zero line is not charged, understood as loop switches and other power outages should be installed on the FireWire, in case of electric shock
The L in the power supply represents the line of phase entry, also known as the FireWire terminal. The N represents the zero line and the incoming line end. It also indicates that the incoming line voltage of this power supply is AC 220V. Hope to help you.
L stands for the positive pole, also known as the FireWire, and N represents the negative pole, also known as the zero line.
