Meaning of Product Safety Symbols
Product failure may result in fire or electric shocks.
Be sure to use the recommended circuit breaker or
fuse. For details, refer to
Recommended circuit
breakers and fuses
on page 25.
The electrical wire may come out and an electric shock
may be caused. Insert the solid wire or ferrule straight into
the terminal block until the end touches the terminal block.
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.
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, conductors, or
cuttings from installation work to enter the Power Supply.
If the circuit breaker has tripped, or the fuse has
blown, there could be a severe failure in the Power
Supply. Do not turn the input ON again.
Ambient Operating and Storage Environments
• Store the Power Supply at a temperature of -40 to +85°C and a
humidity of 95% or less.
• Do not use the Power Supply in areas outside the derating curve
as doing so may result in internal parts occasionally deteriorating
or being damaged.
• Use the Power Supply at a humidity of 95% max.
• 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.
Installation Environment
• Do not use the Product 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.
• Do not use an inverter output for the product. Inverters with an
output frequency of 50/60 Hz are available, but the rise in the
internal temperature of the product may result in ignition or
burning.
• If the input is connected to a UPS, do not connect a UPS with a
square-wave output. Doing so will cause the internal temperature
of the product to increase, possibly causing smoking or burning.
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.
• 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.
• S8VK-W can be used in combinations with a horizontal separation
of less than 15 mm (front, side-by-side mounting) only in cases of
the same model being used.
In such cases, use the product in accordance with a derating curve
with a horizontal separation of less than 15 mm.
Indicates a potentially hazardous situation
which, if not avoided, will result in minor or
moderate injury, or may result in serious
injury or death. Additionally, there may be
significant property damage.
Indicates a potentially hazardous situation
which, if not avoided, may result in minor or
moderate injury or in property damage.
