VII. Installation and use instructions:
1. Unless specified, test conditions are as follows: ambient temperature 25℃, humidity <75%, input voltage 1000VDC and output rated load.
2. When using, please install a SPD of clamping voltage 6KV at the input terminal.
3. In order not to affect the reliability of the product, do not exceed to use the nominal value of the power supply. If you need to change the output parameters, please consult the technical department before using in order to ensure the effect and reliability.
4. If the module fails, please do not repair it by yourself. Please contact the customer service Department as soon as possible.
5. All index test methods in this manual are based on the company's standards.
VIII. Packaging, transportation, storage:
1. Packaging: There is the product name, model, manufacturer's logo, manufacturer's quality department inspection certificate, manufacturing date, etc. on the packing carton.
2. Transportation: This package is suitable for car, ship, plane, train and other transportation, the transportation process should be rainproof, civilized loading and unloading.
3. Storage: When the product is not used, it should be placed in the packing carton, the storage environment temperature and relative humidity should meet the requirements of the product. There should be no corrosive gases or products in the warehouse, and there is no strong mechanical vibration, shock and strong magnetic field. The packing carton should be placed at least 20cm above the ground and protected from water. If the storage time is too long (more than 1 year), it should be re-inspected by professionals before use.
