2.6 Power-on Self-test 
A successful self-test indicates that the purchased power product meets 
delivery standards and is available for normal usage. 
Before operation, please confirm that you have fully understood the safety 
instructions. 
 
  To avoid burning out, be sure to confirm that power voltage matches with 
supply voltage. 
  Be sure to connect the main power socket to the power outlet of protective 
grounding. Do not use terminal board without protective grounding. Before 
operation, be sure that the power supply is well grounded. 
  To avoid burning out, pay attention to marks of positive and negative 
polarities before wiring.
