Safety Precautions
!CAUTION
Minor electric shock, fire, or Product failure may
occasionally occur. Do not disassemble, modify, or repair
the Product or touch the interior of the Product.
Minor burns may occasionally occur. Do not touch the
Product while power is being supplied or immediately
after power is turned OFF.
Fire may occasionally occur. Tighten terminal screws to
the specified torque of 0.74 N·m (M3.5).
Minor injury due to electric shock may occasionally occur.
Do not touch the terminals while power is being supplied.
Minor electric shock, fire, or Product failure may
occasionally occur. Do not allow any pieces of metal or
conductors or any clippings or cuttings resulting from
installation work to enter the Product.
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.
Air
When mounting two or more power supplies side-by-side, allow at
least 10 mm spacing between them, as shown in the following
diagram.
Forced air-cooling is recommended.
10 mm min.
DIN Rail Mounting
S82S
A
B
When mounting to a DIN Rail, lower the S82S onto the Rail until the
Rail stopper clicks into space, hook section A over the edge of the
Rail, and push in the direction of B.
Rail stopper
30 mm min.
To remove the S82S from the DIN Rail, insert a screwdriver into
section C and pull the S82S away from the Rail.
Serial or Parallel Operation
No serial or parallel operation is available.
The positive and negative output terminals of a Dual Output Model
cannot be connected in series to operate.

Minimum Output Current
(S82S-7727 and S82S-7728)
The minimum output current of the S82S-7727 and S82S-7728 is
restricted by the output voltage and control method.
Note: All the outputs of the S82S-7727 and S82S-7728 are controlled
by the +V output. If the +V output current falls to 10% or less of
the rated output, the –V output voltage may drop.
ALL DIMENSIONS SHOWN ARE IN MILLIMETERS.
To convert millimeters into inches, multiply by 0.03937. To convert grams into ounces, multiply by 0.03527.
