(F) mounting is not possible when unit is with case cover, but if

need to operate unit by (F) positioning with case cover, tempera-

ture/load derating is necessary. For more details, please consult

our sales or engineering departments.

The mounting screw should be M3. The hatched area shows the

allowance of metal parts for mounting.

Please be carefull with that metal parts do not touch mounted

parts at front side, where major components are mounted, when

a power supply is installed with them.

4.3 Mounting screw

nWhen 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,

This power supply is the rugged P.C.B. type. Do not drop conduc-

tive object 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 P.C.B like twisting or bending causes the defect of the

unit, so handle the unit with care.
