Do not drop conductiveobjects in the power supply.!At light load, there remains high voltage inside the power supplyfor a few minutes after power OFF.Be careful of electric shock during maintenance.!This power supply is manufactured by SMD technology. Thestress to PCB like twisting or bending causes the defect of theunit, so handle the unit with care.-Please tighten screws in all mounting holes.LHP-16
