Instructions for installation and use:
1.During installation, please follow the above instructions for installation.
2.Before the installation is complete, please check and proofread the wiring on each terminal, make sure that input and output, AC and DC, positive and negative terminals, voltage and current values are correct, prevent the occurrence of reverse connection error, to avoid damage to the power supply and equipment.
3.Please use a multimeter to measure whether the live wire, neutral wire and ground wire are short-circuited and whether the output terminal is short-circuited before power-on.It is best to start no-load when energized.
4.Do not exceed the nominal value of the power supply, so as not to affect the reliability of the product.If you need to change the output parameters of the power supply, please consult the technical department of our company before using the power supply to ensure the use effect and reliability.
5.In order to ensure the safety of use and reduce interference, please ensure that the grounding terminal is reliably grounded (grounding wire greater than AWG18#.
6.In order to extend the life of the power supply, we can provide air duct design solutions.
7.Do not switch the power supply frequently, otherwise it will affect its life.
8.If the power supply fails, please do not repair it without permission. Please contact the customer service Department of our company as soon as possible.
