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.
Minor injury due to electric shock may occasionally
occur. Do not touch the terminals
while power is being supplied.
Working voltage can be 370V max. inside. This
voltage can be also available 30s after the switch off.
Do not allow contact with a conductor after power-on, withstand
voltage testing, or insulation resistance testing. Residual
voltage may cause failure, deterioration, or electrical shock.
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.
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.
• The light ignition may possibly be caused. Ensure that input and
output terminals are wired correctly.
• Be sure to remove the sheet covering the product for machining
before power-ON so that it does not interfere with heat dissipation.
• Always select wire sizes suitable for at least 1.6 times the rated
current to prevent heating and ignition of wire materials due to load
abnormalities. Refer to the wiring manufacturer’s recommended
allowable current and voltage drop specifications for information
when selecting wiring materials.
• The current rating for the output terminal is 5A per terminal.
Make sure to use multiple terminals together if a current
exceeding the terminal rating is used.
• Use wiring materials with a UL recognized temperature of 60
°
C
min. or 60
°
C/75
°
C min.
• Use wiring materials with copper conductors.
• Refer to Input and Output Connectors on page 6 for the model
numbers of the Input and Output Connectors.
Do not insert and remove any connector more than 20 times.
Installation Environment
• Avoid places subject to shock or vibration.
A device such as a contact breaker may be a vibration source. Set
the Power Supply as far as possible from possible sources of
shock or vibration.
• If the Power Supply is used in an area with excessive electronic
noise, be sure to separate the Power Supply as far as possible
from the noise and surge sources.
Ambient Operating and Storage Environments
• Store the product with ambient temperature
−
25 to 75°C, and
relative humidity 25 to 90%.
• The internal parts may occasionally be deteriorated or broken. Do
not use the product outside the derating range.
• Use the product where the relative humidity is 25 to 85%.
• Avoid places where the product is subjected to direct sunlight.
• Avoid places where the product is subjected to penetration of
liquid, foreign substance, or corrosive gas
CAUTION
Indicates a potentially hazardous situation
which, if not avoided, may result in minor or
moderate injury or in property damage.

avoid doing, to prevent failure to operate,
malfunction or undesirable effect on product
performance.
Used to warn of the risk of electric shock under
specific conditions.
Use to indicate prohibition when there is a risk of
minor injury from electrical shock or other source if
the product is disassembled.
Used for general CAUTION, WARNING, or
DANGER precautions for which there is no specified
symbol. (This symbol is also used as the alerting
symbol, but shall not be used in this meaning on the
product.)
Used to warn of the risk of minor injury caused by
high temperatures.
