When installing the power supply with your unit, ensure that the in-

put FG terminal or mounting hole FG is connected to safety

ground of the unit. However when applying the safety agency,

connect the input FG terminal to safety ground of the unit.

This power supply is the rugged PCB type. Do not drop conduc-

tive objects in the power supply.

At light load, there remains high voltage inside the power supply

for a few minutes after power OFF. So, at maintenance, take care

about electric shock.

This power supply is manufactured by SMD technology. The

stress to PCB like twisting or bending causes the defect of the

unit, so handle the unit with care.
