Safety Precautions
Refer to Safety Precautions for All Power Supplies.
Warning Indications
Meaning of Product Safety Symbols
!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.
M3.5: 0.74 to 1.13N

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.
Ambient Operating and Storage Environments
• Store the Power Supply at a temperature of −25 to 75°C and a
humidity of 90% max.
• The internal parts may occasionally deteriorate or be damaged.
Use the Power Supply within the derating curve.
• Use the Power Supply at a humidity of 90% max.
• Do not use locations where liquids, foreign matter, or corrosive
gases may enter the interior of the Power supplies.
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 contractors or other devices that are a vibration
source.
• Install the Power Supply well away from any sources of strong,
high-frequency noise and surge.
Mounting
• Take adequate measures to ensure proper heat dissipation to
increase the long-term reliability of the Power Supply.
Be sure to allow convection in the atmosphere around devices
when mounting.
Do not use in locations where the ambient temperature exceeds
the range of the derating curve.
The S8FS-G015@@@ to S8FS-G150@@@ are cooled by natural
convection. Mount them so that air convection will occur around
them.
The S8FS-G300@@@ and S8FS-G600@@@ are cooled by forced
airflow. Do not allow the ventilation holes to be blocked. The
effectiveness of cooling would be reduced.
• When cutting out holes for mounting, make sure that cuttings do
not enter the interior of the Power supplies.
• The internal parts may occasionally deteriorate and be broken due
to adverse heat radiation. Do not loosen the screws on the Power
Supply.
• If you mount the Power Supply with the holes provided on the
chassis, do not exceed the depth given in the dimensional
diagrams.
Use the following tightening torques.
M3 screws: 0.48 to 0.59 N
·m
M4 screws: 1.08 to 1.32 N
