*1. The value is when both rated output voltage and rated output current are satisfied.
*2. Do not use an inverter output for the product. Inverters with an output frequency of 50/60 Hz are available,
　　but the rise in the internal temperature of the product may result in ignition or burning. If the input is
　　connected to a UPS, do not connect a UPS with a square-wave output. Doing so will cause the internal temperature
　　of the product to increase, possibly causing smoking or burning.
*3. The value is determined according to the Electrical Appliances and Material Safety Act.
*4. Values for a cold start at 25°C. Refer to Inrush Current, Startup Time, Output Hold Time on Catalog for details.
*5. If the output voltage adjuster (V. ADJ) is turned, the voltage will increase by more than the voltage adjustment
　　range. When adjusting the output voltage, confirm the actual output voltage from the product and be sure that the
　　load is not damaged.
*6. The value is when both rated output voltage and rated output current are satisfied. A characteristic when the
　　ambient operating temperature is 25°C.
*7. 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.
*8. When the input voltage is 380 to 480 VAC, this is the maximum variation in the output voltage when the output
　　current is gradually changed within the range of 0 A to the rated output current.
*9. The value is when rated output voltage, rated output current, and room temperature (25°C) are satisfied.
　　Refer to Inrush Current, Startup Time, Output Hold Time on Catalog for details.
*10. At -40 to -25°C, time will be required before the rated output voltage is output after the input voltage is input.
　　 Also, the ripple noise value may exceed the value shown in the above table. (3-phase 380 to 480 VAC input only)
*11. If there is a possibility that the Unit will be subject to vibration or shock, use a steel DIN Rail.
*12. MTBF is calculated according to JEITA RCR-9102.
*13. Refer to Recommended Replacement Periods and Periodic Replacement for Preventive Maintenance on
　　 Catalog for details.
*14. When using 2-phase input, conforms to EN 61000-3-2 under the following condition 960W: At the rated output voltage,
　　 and 80% or less than the rated output current
*15. In order to comply with the safety standards, the input must be connected to the product via the recommended
　　 circuit breaker or fuse. Refer to Recommended Circuit-breakers and Fuses on Catalog for details.
*16. AC input overvoltage categories UL 61010-2-201, EN/IEC 61010-2-201, and CSA C22.2 No. 61010-2-201 are shown
　 　 in the table to the below.

*17. For certification conditions, refer to Standard Compliance blow.
*18. This BIS Standard is an Indian standard that has been in effect for this product since April 2021, and certification has
        been acquired for some models to enable individual product export to India

Standard Compliance

• To comply with PELV output requirements for EN/IEC 60204-1, ground the negative side of the output (-V) to a
　protective earth (PE).
• EN/IEC 61558-2-16
　The S8VK-T was designed based on EN/IEC 61558-2-16.
　Currently, IEC 61558-2-17 has been replaced by IEC 61558-2-16.
　When certification was received for EN/IEC 60204-1 (Machinery Safety), it was necessary to go through a control
　transformer to the control circuits. However, a control transformer is not always necessary for products that
　have been certified for the safety standard for OVCIII or for products that use a transformer that conforms to
　EN/IEC 61558-2-16.
• Safety Standards for a DC Input
　For DC input, EN/IEC 62477-1, EN/IEC 61558-2-16, and LR are subject to safety standards.
　In addition, for DC input, connect the positive voltage to the +L1 terminal and negative voltage to the -L2 terminal.
　For details on selecting a UL-certified fuse, refer to Recommended Circuit-breakers and Fuses on Catalog.
• Conformance to Marine Standards
　Fix an End Plate (PFP-M) to both sides of the unit to hold it in place. (S8VK-T Series)
　Use S82Y-VK90F front-mounting bracket for 480 W.
　Side-mounting brackets are not compliant.
　A noise filter manufactured by SCHAFFNER Corporation (FH3288-10-44-C34-R65) or equivalent should be
　connected to the input terminals. (S8VK-T96024 only)
