How to install the Liechtenstein AC power supply so that it can function as a protection switch?(1)

(9) For the high-voltage module power supply, do not touch the high-voltage dangerous area during use and within 10 minutes after the power outage.
(10) Purchasing principle of module power supply: Generally, switching power supply should be selected for larger power, and linear power supply should be selected for smaller power.
(11) The module power supply cannot be forcibly dismantled, and it will be damaged if it is forcibly dismantled.

How to install the Liechtenstein AC 24V input power supply so that it can function as a protection switch?

Since the air switch and the leakage switch do not have protective functions, when the 24V input power supply is abnormal, a large number of electrical equipment will be damaged. When these accidents occur, it is only necessary to disconnect the 24V input power supply when the 24V input power supply is abnormal, so as not to damage the electrical equipment.

Liechtenstein The three-phase AC power intelligent protector has major electrical fault protection functions such as overvoltage, low voltage, neutral wire disconnection, short circuit, phase loss/opening, etc., and has fault identification, fault indication, voltage before closing, neutral live wire reverse connection, Zero line disconnection, phase loss/phase failure detection, remote monitoring, online parameter modification and software upgrade functions.
