When two or more power supplies are used side by side, position
them with proper intervals to allow enough air ventilation. Ambient
temperature around each power supply should not exceed the
temperature range shown in derating curve.
In case of metal chassis, keep the distance between l & l for to
insulate between lead of component and metal chassis. If it is
less than l & l , insert the insulation sheet between power supply
and metal chassis.

Note:
In the slanted area, the specification of Ripple, Ripple Noise is dif-

Note:
Ventilation is required so that part A of heat sink is below 85 in
any case. Please flow air to the components to the direction of Air
or Air .

(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 unit mounted except below drawings, it is required to con-
sider ventilated environment by forced air cooling for tempera-
ture/load derating. For details, please consult our sales or engi-
neering departments.

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,
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.
