■Before using this product
Be sure to take note of precautions and warnings indicated in this manual when using this product. Improper usage may
lead to electric shock or fire. Be sure to read this instruction manual thoroughly before using this product.
■Precautions
● Avoid touching the baseplate and the case of this product because they get hot.
● There are high voltage and high temperature components within this product. Refrain from disassembling this product
or touching its internal components as this may lead to electric shock or burn.
● To avoid unexpected accident from placing hands or face near the unit during operation.
● Verify that connection to input, output and signal terminals are correct as indicated in this instruction manual.
● For acquisition of various Safety Standards and safety improvement, be sure to use an external fuse.
● This product is designed for installation on electronic equipment.
● For input terminals of 24 V input models, apply a voltage from a primary source with reinforced or double insulation.
● Output voltage of this product is considered to have hazardous energy level (voltage of 2V and above with power of
240W and above) and must not have physical contact with operator. Protection must be provided on this module when
installed on equipment to prevent physical contact with service technician himself or accidentally dropped tools during
repair. Before repair, be sure to turn off the input source and confirm that input and output voltage have drop down to a
safe level.
● Application circuit or component values described in this instruction manual are for reference only. When designing
circuit, be sure to verify actual circuit operation before determining final application circuit or component values.
● Contents of this instruction manual are subject to change without notice. When using this product, please refer to latest
data sheet to satisfy this product specification.
● No part of this document may be copied or reproduced in any for, or by any mean without prior written consent of
TDK-Lambda.
