BEFORE USING THE POWER SUPPLY UNIT
Be sure to read this instruction manual thoroughly before using this product. Pay attention to all cautions and warnings before using this product.
Incorrect usage could lead to an electrical shock, damage to the unit or a fire hazard.
DANGER
Never use this product in locations where flammable gas or ignitable substances are present. There are risks of igniting these substances and
exploding by an arcing.
WARNING
Do not touch this product or its internal components while circuit is live, or shortly after shut down. There may be high voltage or high
temperature present and you may receive an electric shock or burn.
When this product is operating, keep your hands and face away from it as you may be injured by an unexpected situation.
Do not make unauthorized changes to this product, otherwise you may receive an electric shock and void your warranty.
Do not drop or insert anything into this product. It might cause a failure, fire and electric shock.
Do not use this product under unusual condition such as emission of smoke or abnormal smell and sound etc. It might lead to fire and electric
shock. In such cases, please contact us. Do not attempt repair by you, as it is dangerous for the user.
Do not operate these products in the presence of condensation. It might lead fire or electric shock.
CAUTION
This power supply is designed and manufactured for use within an end product such that it is accessible to SERVICE ENGINEERS only.
Confirm connections to input/output terminals are correct as indicated in the instruction manual before switching on.
Input voltage, Output current, Output power, ambient temperature and ambient humidity should be kept within specifications, otherwise the
product will be damaged.
Do not operate and store this product in an environment where condensation might occur. In such case, waterproof treatment is necessary.
Do not use this product in environment with a strong electromagnetic field, corrosive gas or conductive substances.
For applications, which require very high reliability (Nuclear related equipment, medical equipment, traffic control equipment, etc.), it is
necessary to provide a fail-safe mechanism in the end equipment.
Do not inject abnormal voltages into the output of this product. The injection of reverse voltage or over voltage exceeding nominal output
voltage into the output terminal might cause damage to internal components.
Never operate the product under over current or short-circuit conditions for more than 30 seconds, or outside its specified Input Voltage Range.
Insulation failure, smoking, burning or other damage may occur.
The outputs of this product may, under fault conditions, exceed SELV voltage limits. Therefore the outputs must be earthed in the end
equipment to maintain SELV. If the outputs are not earthed, they must be considered hazardous and must not be made user accessible.
This product has used Power Thermistor to protect the circuit from Inrush Current. Frequent repetition of input on/off might cause damage to
internal components because of generating surge current.
Breaking of internal fuse is considered internal failure. In such cases, please contact us.
The information in this document is subject to change without prior notice. Please refer to the latest version of the data sheet, etc., for the most
up-to date specifications of the product.
