Operation Guide and Notice:

1. To check the marked input voltage, output voltage and current according to your requirements;
2. To switch in the input voltage according to wiring mark and to connect FG terminal with case or earth; Wiring should be done under the condition of powering off;
3. To wire in loading for all wiring terminals evenly;
4. Don not wire in the DC input power supply wrongly, the positive and negative polarity should be taken into consideration;
5. Overload or long-term full load is not desirable.
6. Excellent ventilation;
7. Nonprofessional must not dismount power supply to avoid the electric shock hazard.
