*1. Do not use an inverter output for the Power Supply. Inverters with an output frequency of 50/60 Hz are available, but the
    rise in the internal temperature of the Power Supply may result in ignition or burning.
*2. For a cold start at 25°C. Refer to Engineering Data on Catalog for details.
*3. If the output voltage adjuster (V. ADJ) is turned, the voltage will increase by more than +15% of the voltage adjustment
    range. When adjusting the output voltage, confirm the actual output voltage from the Power Supply and be sure that
    the load is not damaged.
*4. A characteristic when the ambient operating temperature is between –25 to 60°C.
*5. To reset the protection, turn OFF the input power for three minutes or longer and then turn it back ON.
*6. Safety Standard for a DC Input
     The following safety standards apply to a DC input: UL 60950-1,
     cUR (CSA C22.2 No.60950-1), EN 50178, EN60950-1.
     For a DC input, safety is ensured by external fuse.
     Select an external fuse the meets the following conditions.
