*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 Data Sheet for details.
*3. If the output voltage adjuster (V. ADJ) is turned, the voltage will increase by more than 29.5 VDC 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 70°C.
*5. Refer to Overvoltage Protection on Data Sheet for the time when input voltage shuts off and input turns on again.
*6. To meet safety standards, the S8VK-T must be protected with an external circuit-breaker or a fuse.
      Be sure to use an external circuit-breaker or a fuse. Refer to Precautions for Safe Use on Data Sheet for details.
*7. The following supplementary Fuse/Circuit Breaker must be installed in accordance with NEC.:
      Model FAZ-D5/3-NA, FAZ-D5/3-RT or FAZ-D5/3-DU, EATON INDUSTRIES (AUSTRIA) GMBH (E235139),
      Model KLKD5, LITTELFUSE INC. (E10480)
*8. Safety Standards for a DC Input
      The following standards apply to a 450 to 600 VDC input: UL 60950-1, EN 50178, EN 60950-1, and Lloyd's standards.
*9. In the case of using side-mounting bracket (S82Y-VK10S, S82YVK20S), Lloyd's Standards are not applicable.
*10. The value is when rated output current is 50% or less, the ambient operating temperature is 40°C or less, standard
        mounting, and rated input voltage.
*11. The value is when both rated output voltage and rated output current are satisfied.
*12. 380 to 480 VAC input, in the range of 0 A to the rated output current.
*13. This is the maximum variation in the output voltage when the input voltage is gradually changed within the allowable
        input voltage range at the rated output voltage and rated output current.
*14. Use at 26.4 VDC or lower for 2-phase input.
*15. The S8VK-T Power Supply conforms to EN 61000-3-2 under the following conditions for 2-phase input.
        480 W: rated output voltage, and 65% or less of rated output current
        960 W: rated output voltage, and 45% or less of rated output current
*16. The S8VK-T Power Supply conforms to EMI under the following conditions for 2-phase input.
         480 W: Conforms to class B: rated output voltage, and 65% or less of rated output current/
                      Conforms to class A: rated output voltage, and 65% to 100% of rated output current
         960 W: Conforms to class B: rated output voltage, and 45% or less of rated output current/
                      Conforms to class A: rated output voltage, and 45% to 100% of rated output current
*17. 480 W: rated output voltage, and 50% or less of rated output current.
        960 W: rated output voltage, and 92.5% or less of rated output current.
*18. When using 2-phase input. Refer to 2-Phase Input Operation For 960 W Model in Precautions for Safe Use on Data
        Sheet for details.
