Keep this Instruction Manual close at hand and use it for reference during operation.
When using S8VS- 48024A- or S8VS-48024B-, read the “S8VS Operation Manual” together without fail.

Precautions for Safe Use

Installing/Storage Environment
- Store the product with ambient temperature –25 to +65°C, and relative humidity 25 to 90%.
- (Only for S8VS-48024A-) To maintain the function of the Maintenance forecast monitor function during storage over an extended period of time, satisfy the following conditions.
- Store the product with temperature –25 to +30°C and humidity 25 to 70% if the storage period exceeds three months.
- The internal parts may occasionally deteriorate and be broken due to adverse heat radiation depending on the mounting status. The maintenance forecast monitor function may not work correctly. Do not use the product in any way other than the standard mounting direction.
- The internal parts may occasionally be deteriorated or broken. Do not use the product in the condition over the derating (at the portion of derating curve).
- Use the product where the relative humidity is 25 to 85%.
- Avoid places where the product is subjected to direct sunlight.
- Avoid places where the product is subjected to penetration of liquid, foreign sub-stance, or corrosive gas.
- Avoid places subject to shock or vibration.
- A device such as a contact breaker may be a vibration source. Set the Power Supply as far as possible from possible sources of shock or vibration.
- If there is a possibility that the Unit will be subjected to vibration or impact, metallic filings may be generated by abrasion. In this situation, use a metal DIN Rail.
- If the Power Supply is used in an area with excessive electronic noise, be sure to separate the Power Supply as far as possible from the noise sources.
- The internal parts may occasionally deteriorate and be broken due to adverse heat radiation. Do not loosen the screw on the side face of the main body.
Arrangement/Wiring
- Connect the ground completely. A protective earthing terminal stipulated in safety standards is used. Electric shock or malfunction may occur if the ground is not connected completely.
- The light ignition may possibly be caused. Ensure that input and output terminals are wired correctly.
- Use the following material to the wire to be applied to the product for preventing from the occurrence of the smoking or ignition caused by the abnormal load.

  * Provide maximum 15 A overcurrent protection on each positive output wire.
  * Do not apply more than 100N force to the terminal block when tightening it.
  * Be sure to remove the sheet covering the product for machining before power-on.
  * (Only for S8VS-48024-F) Do not insert more than one line for each terminal.
  * (Only for S8VS-48024-F) Insert a tool into the tool insertion hole to insert or remove an I/O wire. After connecting a wire, but sure that it is firmly connected. Never insert a wire into the tool insertion hole.

Output Voltage Adjustment
- The output voltage adjuster (V.A DJ) may possibly be damaged. Do not add unnecessary power.
- Do not exceed the rated output capacity and current after adjusting the output voltage.

  * Mounting Space

Install the power supply so that the air flow circulates around the power supply, as the power supply is designed to radiate heat by means of natural air flow.

  * Direction of air circulation
  * 75 (mm) or more
  * 75 (mm) or more
  * 20 (mm) or more
  * Derating Curve
  * Under reduced voltage conditions : 85 to 95 VAC
  * Normal operating voltage : 100 to 240 VAC (Voltage tolerance : 95 to 264 VAC)
  * Input Voltage Tolerance

85 to 264 VAC

  * Parallel Operation

The product is not designed for parallel operation.

  * Output Voltage Adjustment

Default Setting: Set at the rated voltage
Adjustable Range: Adjustable with “V.ADJ ” on the front surface of the product from – 10% to +15% of the rated output voltage.
Turning clockwise increases the output voltage, and turning counterclockwise decreases the output voltage.

  * Dielectric Strength Test

Rated dielectric strength:
3000VAC between and <output terminals , , , , together > for 1 minute.
When testing, set the cutoff current for the withstand voltage test device to 20mA.
Notes:

  * Sudden switching of 3000VAC may possibly cause a voltage surge, damaging the power supply. Increase/decrease test voltage gradually.

Be sure to short-circuit all the output terminals and the Alarm output terminals of the power supply to protect the power supply from damage.

  * Insulation Resistance Test

When testing the insulation resistance of the power supply, use a DC ohmmeter at 500 VDC.
Note:
Be sure to short-circuit all the output terminals and the Alarm output Terminals of the power supply to protect the power supply from damage.

  * Overload Protection

The load and the power supply are automatically protected from overcurrent damage by this function.
When the output current returns within the rated range, overload protection is automatically cleared.
Notes:

  * If operation is continued when the Power Supply has been short-circuited or in an overcurrent status, internal parts in the Power Supply may occasionally deteriorate or be damaged.

The internal parts may possibly be deteriorated or damaged. Do not use the product for applications where the load causes frequent inrush current and overload.

  * Overvoltage Protection

This power supply automatically protects itself and the load from overvoltage.
Overvoltage protection is activated if the output voltage rises above approx. 130% of the rated output voltage.
To reset the power supply, leave the power supply off for more than 3 minutes and then turn it on again.
Note:
Be sure to clear the cause of the overvoltage, before turning on the power supply.

  * Alarm Output(Only for S8VS-48024A/B)

Transistor Output: 30VDC max., 50 mA max.
Residual voltage upon power-on: 2 V or smaller.
Leakage current upon shutoff: 0.1 mA or smaller.
Note:
For the undervoltage alarm function, maintenance forecast monitor function, and total run time monitor function, refer to the “S8VS Operation Manual”.

  * In Case there is No Output Voltage

of an overload or overvoltage condition, or may be due to the functioning of an latching protective device. The latching protection may operate if a large amount of surge voltage such as a lightening surge occurs while turning on the power supply. In case there is no output voltage, please check the following points before contacting us:
Check the Overload Protected Status:

  * Check whether the load is in overload status or is short- circuited. Remove wires to load when checking.
  * Attempt to clear the overvoltage or latching protection function: Turn the power supply off once, and leave it off for at least 3 minutes. Then turn it on again to see if this clears the condition.
  * Conformance to EU Directives

Refer to the catalogue and this instruction manual for details on the operating condition for EMC-compliance.
Warning: This is a class A product. In a residential, commercial or light industrial environment it may cause radio interference. This product is not intended to be installed in a residential environment; in a commercial and light industrial environment with connection to the public mains supply, the user may be required to take adequate measures to reduce interference.

  * Wiring to Alarm Output Terminal

Push the button at the center of the terminal block to insert or pull the wire out of the terminal.
After the insertion, pull gently on the wire to make sure that it will not come off and the wire is securely fastened to the terminal block.
