Safety Precautions
Refer to Safety Precautions for All Power Supplies.
Warning Indications
Meaning of Product Safety Symbols
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.
S8FS-C015@@J: 4.25 to 5.13 lb-in (0.48 to 0.58 N·m)
Other than S8FS-C015@@J: 6.55 to 7.78 lb-in (0.74
to 0.88 N·m)
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 40 to 85C and a
humidity of 10% to 95%.
The internal parts may occasionally deteriorate or be damaged.
Use the standard mounting method only. Do not use the Power
Supply outside the derating range.
Use the Power Supply at a humidity of 20% to 90%.
Do not use the Power Supply in locations subject to direct sunlight.
Do not use the Power Supply in 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. Install the Power Supply away from contactors and
other parts and devices that are sources of vibration.
Install the Power Supply well away from any sources of strong,
high-frequency noise and surge.
Input Voltage Selector Switch
For 100-W or higher models, the input voltage is factory-set to 200
to 240 V.
To use an input voltage of 100 to 120 VAC, change the input
voltage selector switch to the 100 to 120 VAC setting.
To use a DC input, set the input voltage selector switch to the 200
to 240 VAC setting.
Minor electric shock may occasionally occur. Do not operate the
input voltage selector switch while power is being supplied.
Mounting
Take adequate measures to ensure proper heat dissipation to
increase the long-term reliability of the Power Supply.
For models other than the S8FS-C350, be sure to allow
convection in the atmosphere around devices when mounting. Do
not use the Power Supply in locations where the ambient
temperature exceeds the range of the derating curve.
For the S8FS-C350: Forced air cooling with a fan is used. Do
not allow the ventilation holes to be blocked. The effectiveness of
cooling would be reduced.
The internal parts may occasionally deteriorate or be damaged.
Use the standard mounting method only. Do not use the Power
Supply outside the derating range.
If you mount the Power Supply by using the screw holes provided
on the chassis, the screws should preferably not penetrate beyond
the exterior by more than 3 mm inside the Power Supply. If you use
screws that are longer than this, make sure that they do not
penetrate beyond the depth given in the dimensional diagram. Use
the following tightening torque.
0.48 to 0.59 N·m for M3 screws
1.08 to 1.32 N·m for M4 screws
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 or be damaged due
to adverse heat radiation. Do not loosen the screws on the Power
Supplies.
