    Introduction Introduction Thank you for purchasing the HIOKI Model SM7860 series Power Source Unit. To obtain maximum performance from the device, please read this manual first, and keep it handy for future reference. Confirming Package Contents When you receive the device, inspect it carefully to ensure that no damage occurred during shipping.

  • Page 6: Safety Information

    Safety Information Safety Information This device is designed to comply with IEC 61010 Safety Standards, and has been thoroughly tested for safety prior to shipment. However, mishan- dling during use could result in injury or death, as well as damage to the device.

  • Page 7: Operating Precautions

    Before using the device for the first time, verify that it operates normally to ensure that no damage occurred during storage or shipping. If you find any dam- age, contact your dealer or Hioki representative. Device Installation Operating temperature and humidity : 0 to 40°C at 80%RH or less (non-condensing)
  • Page 8 Operating Precautions Installing To prevent overheating, be sure to leave the specified clearances around the unit. • Vents must not be obstructed. • When rack-mounting the device, fans must be installed above or on top of the rack to ensure proper ventilation. Be sure that the rack is adequately venti- lated so that the internal temperature remains at or below 40°C.
  • Page 9 Cable is undamaged and that no bare conductors are improperly exposed. Using the device in such conditions could cause an electric shock, so con- tact your dealer or Hioki representative for replacements. • Avoid stepping on or pinching cables, which could damage the cable insula- tion.
