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 0.98 N·m.
Minor injury due to electric shock may occasionally occur.
Do not touch the terminals while power is being supplied.
Always close the terminal cover after wiring.
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.

■ Precautions for Safe Use

Mounting
Take adequate measures to ensure proper heat dissipation to
increase the long-term reliability of the product.
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 two or more Power Supplies side-by-side, allow at
least 10 mm spacing between them, as shown in the following
illustration.
Forced air-cooling is recommended.
10 mm min.
To mount the Power Supply on a DIN rail, hook portion (A) of the
Power Supply to the rail and press the Power Supply toward direction
(B).

To dismount the Power Supply, pull down portion (C) with a flat-blade
screwdriver and pull out the Power Supply.
When tightening the terminals, do not tighten the terminal block to a
torque greater than 75 N.
Selection of 100 or 200 VAC Input
Voltage
(S82K-@09024/-@10024)
Select a 100 V or 200 V input by shorting or opening the Input Volt-
age Selector Terminals, as shown in the following diagram.
(The default setting is 200 V.)
100 V Input
Use the short bar to short-circuit
terminals 7 and 8.
200 V Input
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.

INPUT
When connecting the Power Supplies in series with an operation
amplifier, connect diodes to the output terminals as shown by the
dotted lines in the figure. No diodes are required with S82K 90-W/
100-W models.
Switch Mode Power Supply
