Do not operate these units under condensation condition. It may cause fire and electric shock. CAUTION As a component part, compliance with the standard will be based upon installation in the final application. This product must be installed in a restricted access location, accessible to authorized competent personnel only. These AC to DC converters have reinforced insulation between the input and the output. The outputs of these products are energy hazards. All models with an output greater than 28V model are considered to be non-SELV. As such, the instructions for use must refer to these energy hazardous outputs and Non-SELV outputs in that the outputs must not be accessible to the operator. The installer must also provide protection against inadvertent contact by a service engineer. The equipment has been evaluated for use in a Pollution Degree 2 environment. This power supply is primarily designed and manufactured to be used and enclosed in other equipment. Confirm connections to input/output terminals and signal terminals are correct as indicated in the instruction manual. Attach an HBC external fuse to each module to ensure safety operation and compliance to each safety standard approval. The recommended input fuse rating within the instructions is as follows: -15AHBC, 250V fast acting fuse. The breaking capacity and voltage rating of this fuse may be subject to the end use application. Input voltage, output current, output power, ambient temperature and ambient humidity should be used within specifications, otherwise the unit will be damaged. For application equipment, which requires very high reliability (nuclear related equipment, traffic control equipment, medical equipment, etc.), please provide fail safety function in the equipment. Do not use the product in environment with strong electromagnetic field, corrosive gas and conductive substance. Do not operate and store this unit at an environment where condensation occurs. 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 may occur to the unit. 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 240VA or more.) Prevention from direct contact with output terminal is highly necessary. While installing or servicing this power supply unit, avoid dropping tools by mistake or direct contact with output terminal. This might cause an electric shock. While repairing this power supply unit, the AC input power must be switched off and the input and output voltage should be level. To maintain the SELV output for outputs less than 28VDC, under fault conditions, the output must be connected to earth in the final application. The application circuits and their parameter are for reference only. Be sure to verify effectiveness of application circuits and their parameters before finalizing circuit design. Do not inject abnormal voltage to output terminal and signal terminal from the outside. The injection of reverse voltage or over voltage exceeding nominal output voltage to output terminals might cause damage to internal components.
