BEFORE USING THE POWER SUPPLY UNIT
Be sure to read and understand 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 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.
•
While 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 the product. It might lead to a failure, fire or electric shock.
•
Do not use this product if abnormal conditions such as emission of smoke and/or abnormal smell or audible noise, etc… are present. It might
lead to fire and/or electric shock. In such cases, please contact TDK Lambda. Do not attempt repair by yourself, as it is dangerous for the user.
•
Do not operate these products in the presence of condensation. It might lead to fire or electric shock.
CAUTION
•
This power supply is designed and manufactured for use within an end product such that it is accessible only to trained SERVICE ENGINEERS.
•
Confirm that the connections to input/output terminals, and signal terminals are correct as specified in this instruction manual before turning
on the power.
•
Input voltage, Output current, Output power, ambient temperature, case temperature, and ambient humidity should be kept within the
specifications, otherwise the product may be damaged.
•
Do not operate and store this product in an environment where condensation might occur. In such case, waterproof treatment is necessary.
•
The equipment has been evaluated for use in a Pollution Degree 2 environment.
•
Do not use this product in environment with a strong electromagnetic field, corrosive gas or conductive substances.
•
For applications, which require very high reliability, such as 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 terminal or signal terminal of this product. The injection of reverse voltage or over voltage
exceeding nominal output voltage into the output terminal or signal terminal might cause damage to internal components.
•
Never operate the product under the over-current or short circuit conditions. Failure or other damage may occur.
•
The output voltage of this power supply unit is considered to be a hazardous energy level (The voltage is 2V or more and the electric power
is 240W or more). It must not be made accessible to users. Protection must be provided for Service Engineers against indirect contact with
the output terminals and/or to prevent tools being dropped across them. While working on this product, the AC input power must be switched
off, and the input, output, +VBus, and -VBus terminal voltages should be at a safe level.
•
The application circuits and their parameters are for reference only. Be sure to verify effectiveness of these circuits and their parameters
before finalizing the circuit design.
•
Use a Fast-Blow external fuse to each module to ensure safe operation and compliance with the safety standards to which it is approved. The
recommended input fuse rating within the instructions is as follows: 10A, 250V fast acting fuse. The breaking capacity and voltage rating of
this fuse may be subject to the end use application.
