Instruction Manual 

 

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. 

 

WARNING

 

·

 

Do not touch this product or its internal components while it is in operation, or within 5 seconds of shut down. There may be high voltage 

or high temperature present and you may receive an electric shock or burn. 

 

·

 

When the product is operating, keep your hands and face away from it as you may be injured by flying debris in the event of a fault. 

·

 

Do not make unauthorized changes to this product, otherwise you may receive an electric shock and void your warranty. 

·

 

Do not use this product in the event of the emission of smoke or abnormal smell and sound etc. It might lead to fire and/or electric shock. 

In such cases, please contact us. 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 and/or electric shock. 

 

 

·

 

Do not drop or insert anything into the product. It might lead to a failure, fire and/or electric shock.

 

 

CAUTION

 

 

·

 

This power supply is designed for use within an end product such that it is accessible to SERVICE ENGINEERS only. 

·

 

Confirm connections to input/output terminals and signal 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. 

·

 

Never operate the unit under over current or shorted conditions for 30 seconds or more and out of Input Voltage Range as specification. Insulation failure, 

smoking, burning or other damage might occur to the unit.

 

·

 

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, traffic control equipment, etc.), it is necessary to provide a 

fail safe mechanism in the end equipment. 

·

 

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. 

·

 

No part of this document may be copied or reproduced in any form without prior written consent of TDK-Lambda. 

·

 

Do  not  inject  abnormal  voltages  into  the  output  or  signal  of  this  product.  The  injection  of  reverse  voltage  or  over  voltage  exceeding 

nominal output voltage into the output or signal terminals might cause damage to internal components. 

·

 

Operation of this product under over-current or short circuit conditions can result in damage. Failures of the product under these conditions 

have been assessed and are considered to be safe within the meaning of IEC/EN/UL/CSA 60950-1. 

·

 

This  product  contains  a  printed  circuit  board  utilizing  surface  mounted  devices.  PCB  stress  such  as  bending,  twisting  etc  could  cause 

damage. Therefore, please handle with care. 

·

 

In order to maintain SELV output, the base-plate must be protectively earthed in the end application. Where the base-plate is not earthed, 

the output must be considered hazardous and must not be made user accessible. 

·

 

The  output  of  this  product  may,  under  fault  conditions,  exceed  SELV  voltage  limits.  Therefore  the  output  must  be  earthed  in  the  end 

equipment to maintain SELV. If the output is not earthed, they must be considered hazardous and must not be made user accessible. 

·

 

For input terminal of this product, connect DC input source with reinforced insulation or double insulation. 

·

 

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 an HBC external fuse to each module to ensure safe operation and compliance with the Safety Standards to which it is approved.
