<span style="color: rgb(51, 51, 51); font-size: 14px;" helvetica?,?sans-serif?;font-size:9pt;?="">1, the installation, use a length of less than 4mm screw fixing the power supply reliability.
<span style="color: rgb(51, 51, 51); font-family: ;" helvetica?,?sans-serif?;font-size:9pt;?="">2, before the installed power run, check and proofread each wiring terminals on, make sure the input and output, AC and DC, positive and negative voltage
And current values such as the right to eliminate wrong connection reverse phenomenon, to avoid damage to the power supply and user equipment.
3. Use a multimeter to measure power before hot, neutral and ground short circuit, the output is shorted; load when power is the best start.
4. Do not exceed the power supply when using the nominal value, so as not to affect the reliability of the product. To change the power supply output parameters, the power supply to the customer before using our technical
Surgery department consulted to ensure the use of the product and reliability.
5, in order to ensure the safety and reduce the use of interference, ensure reliable grounding ground (grounding wire more than AWG18 #).
6, in order to extend the life of power, our company can provide duct design solutions.
7. Do not frequent switching power supply, or affect their life.
8, such as power failure, please do not repair them, please contact the company as soon as possible to resolve.
