Safety Precautions
Refer to Safety Precautions for All Power Supplies.
!CAUTION
Minor electric shock, fire, or Product failure may
occasionally occur. Do not disassemble, modify, or repair
the Product or touch interior of the Product.
Minor burns may occasionally occur. Do not touch the
Product during power is being supplied or immediately
after power is turned OFF.
Minor injury may occasionally occur due to electrical
shock. Do not touch the terminals while power is being
supplied. Also, be sure to close the terminal cover after
wiring the terminals.
Fire may occasionally occur. Tighten terminal screws to
the specified torque.
Precautions for Safe Use
Mounting
• The long-term reliability of the S8AS can be increased by installing
it properly and providing sufficient heat dissipation. Use the S8AS
within the derating curve. The S8AS is designed to radiate heat by
means of natural air circulation. Provide appropriate space as
shown below to allow air flow around the Power Supplies.
• Poor heat dissipation resulting from improper installation
conditions may occasionally deteriorate or damage internal parts
and also cause the maintenance forecast monitor function to not
operate properly. Do not use any mounting orientation other than
a standard one.
• Poor heat dissipation may deteriorate or damage internal parts. Do
not loosen the screws on the side of the Product.
• Do not allow any pieces of metal or conductors, or any clippings or
cuttings resulting from installation work to enter the Product.

Attachment to the DIN Rail
To mount the block on a DIN Rail, until
it makes a clicking sound, pull down
A
the Rail stopper hook portion (A) of the
Block onto the Rail, and press the
Block in direction (B) to lock it in place.

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

Wiring
• Connect the ground completely. The ground is a protective earth
(PE) terminal specified in safety standards. If the ground is not
connected completely, electric shock or malfunction may occur.
• Minor fire may possibly occur. Ensure that input and output
terminals are wired correctly.
• Heat generated by wiring materials may cause the temperature of
internal parts to increase, which may result in deterioration of or
damage to the internal parts. Select the wiring materials according
to the current that is being used. Using the wiring materials, torque,
and wire stripping lengths in the following table is recommended to
prevent smoke or fire of the wire material due to an abnormal load.
