Precautions
!Caution
Be sure to connect the grounding line. Not doing so may result in
electric shock.
!WARNING
Do not attempt to disassemble the Power Supply or touch its inter-
nal parts while power is being supplied. Doing so may result in
electric shock.
Do not touch the terminals of the Power Supply within one minute
after power has been turned OFF. Doing so may result in electric
shock due to a residual voltage.
Do not touch the S8PS or heat radiation fin while the power is be-
ing supplied or immediately after the power is turned OFF. Other-
wise, a skin burn may result from the hot Switching Power Supply
or radiator.
Mounting
To improve and maintain the reliability of the Power Supply over a
long period of time, adequate consideration must be given to heat
radiation.
The Power Supply is designed to radiate heat by means of natural
air-flow. Therefore, mount the Power Supply so that air flow takes
place around the Power Supply.
When mounting the Power Supply, mounting it to a metal plate is rec-
ommended.
Forced air-cooling is highly recommended.
It is recommended that the clearance around the Power Supply be
larger than those shown on page page 71 under Standard Installa-
tion.
Generating Output Voltage (±)
An output of ± can be generated by using two Power Supplies as
shown below, because the Power Supply produces a floating output.

Series Operation
Only models with power ratings of 100/150 W allow series operation.
As shown in the following diagram, the output voltage from each
Switching Power Supply can be added.

Parallel Operation
Only 300- and 600-W models can be in parallel operation provided
that they are operated under 90% of the ratings. Do not operate any
other models in parallel.
Make sure that the thickness and the length of all wires connected to
the load are the same to ensure that the wires will have no voltage
drop differences.

Fan Replacement
The service life of the fan is approximately 50,000 hours (at 25°C).
The service life varies, however, depending on the ambient tempera-
ture or other surrounding environmental conditions such as dust. As
a preventive maintenance measure, replace the fan within two years
if it is used at an ambient temperature of 40°C.
Fans are available as replacements.
Model: S82Y-JFAN
Fan Set:
Fan (above), four M4 x 35 sems screws, instruction sheet, and pack-
ing case
Replace the fan as shown in the following illustration.
