Wiring
• Connect the ground completely. A protective earthing terminal
stipulated in safety standards is used. Electric shock or malfunction
may occur if the ground is not connected completely.
• Minor fire may possibly occur. Ensure that input and output
terminals are wired correctly.
• Do not apply more than 75 N force to the terminal block when
tightening it.
• Be sure to remove the sheet covering the Product for machining
before power-ON so that it does not interfere with heat dissipation.
• Use the following material for the wires to be connected to the
S8JX to prevent smoking or ignition caused by abnormal loads.

Installation Environment
• Do not use the Power Supply in locations subject to shocks or
vibrations. In particular, install the Power Supply as far away as
possible from contactors or other devices that are a vibration
source.
• Install the Power Supply well away from any sources of strong,
high-frequency noise and surge.
Ambient Operating and Storage Environments
• Store the Power Supply at a temperature of −25 to 65°C and a
humidity of 25% to 90%.
• The Internal parts may occasionally deteriorate or be damaged.
Do not use the Power Supply outside the derating range (i.e., the
area shown by shading A in the derating curve diagram on
page 13.)
• Use the Power Supply at a humidity of 25% to 85%.
• Do not use the Power Supply in locations subject to direct sunlight.
• Do not use locations where liquids, foreign matter, or corrosive
gases may enter the interior of the Product.
Overload Protection
• Internal parts may possibly deteriorate or be damaged if a short-
circuited or overload state continues during operation.
• Internal parts may possibly deteriorate or be damaged if the Power
Supply is used for applications with frequent inrush current or
overloading at the load end. Do not use the Power Supply for such
applications.
Charging a Battery
When connecting a battery at the load, connect an overcurrent
limiting circuit and overvoltage protection circuit.
Output Voltage Adjuster (V.ADJ)
• The output voltage adjuster (V.ADJ) may possibly be damaged if it
is turned with unnecessary force. Do not turn the adjuster with
excessive force.
• After completing output voltage adjustment, be sure that the output
capacity or output current does not exceed the rated output
capacity or rated output current.
DIN Rail-mounting
To mount the Power Supply to a DIN
Rail, pull down the rail stopper until
you hear it clicks open, hook portion
(A) of the Power Supply onto the DIN
Rail, press the Power Supply in
direction (B), and then push up the rail
stopper to lock the Power Supply in
place.

To dismount the Power Supply, pull
down portion (C) with a flat-blade
screwdriver and pull out the Power
Supply.

Series Operation
Two power supplies can be connected in series. The (±) voltage
output can be accomplished with two Power Supplies.

Note: 1. If the load is short-circuited, a reverse voltage will be
generated inside the Power Supply. If this occurs the Power
Supply may possibly deteriorate or be damaged. Always
connect a diode as shown in the figure. Select a diode
having the following ratings.
Type
Schottky Barrier diode
Dielectric strength (VRRM) Twice the rated output voltage or above
Forward current (IF)
Twice the rated output current or above
2. Although Products having different specifications can be
connected in series, the current flowing through the load
must not exceed the smaller rated output current.

Parallel operation is possible under 80% of the rated value.
• To operate in parallel, set the switch to the "PARALLEL" side.
• The length and thickness of each wire connected to the load must
be the same so that there is no difference in voltage drop value
between the load and the output terminals of each Power Supply.
• It is desirable to set the same value on the voltage adjuster of each
Power Supply.
