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
