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.
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 might 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 electrical 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.
This information in this document is subject to change without prior notice. For actual design-in, please refer to the
latest publications of data sheet, etc., for the most up-to date specifications of the unit.
