Instructions before use:

Before power check:Before storage and transportation, the power supply should check the damage during transportation,Is there any difference in appearance?,Whether the power line and the connection terminal are out of shock and whether it is damp or not, if the above phenomenon occurs, it should be dealt with promptly.

Wiring: connect the safety grounding wire and input power line (the required section area is large enough). Make sure the connection is correct and the joint is firm.

No load electricity: connect upAC220VOr AC110V, using multimeter to measure the output, whether or not there isDC Voltage output.

The fan is an important part of the machine. Please don't block the inlet and outlet of the fan when you work.

- when the high temperature in thermal shutdown temperature threshold, the machine will automatically stop working and make sure not to be damaged; when the temperature slightly will automatically start the restoration work is reduced.

Caution: only when the power supply test is normal, can the equipment be connected with the electric load equipment
