4 Assembling and
Installation Method
4.1 Installation method
nWhen 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.
LEA ^{nIn case of metal chassis, keep the distance between l1 & l2 for to}
insulate between lead of component and metal chassis. If it is
less than l1 & l2, insert the insulation sheet between power supply
and metal chassis.

4.2 Derating
nThe operative ambient temperature is different by with / without
case cover or mounting position. Please refer drawings as below.
nIn case , ventilation must keep the temperature of C119 below
85 . See External View for the location of C119.
Note: In the hatched area, the specification of Ripple, Ripple Noise
is different from other area.
Please be careful of electric shock or earth leakage in case of
temperature measurement, because C119 is live potential.
