Precautions for Safe Use

Installation and Storage Environment

Store the Product at a temperature of −25 to 75°C and a humidity of 90% or less.
Take adequate measures to ensure proper heat dissipation to increase the long-term reliability of the Product.
The S8FS-G015 to S8FS-G150 are cooled by natural convection. Mount them so that air convection will occur around them.
The S8FS-G300 and S8FS-G600 are cooled by forced airflow. Do not allow the ventilation holes (provided at fan mounted side and the opposite side) to be blocked. The effectiveness of cooling would be reduced.
The internal parts may occasionally deteriorate or be damaged. Do not use the Product beyond the derating curve range.
Refer to the Product catalog for the derating curve for each mounting direction.
Use the Product at a humidity of 90% or less.
Avoid places where the Product is subjected to direct sunlight.
Avoid places where the Product is subjected to penetration of liquid, foreign substance, or corrosive gas.
Avoid places subject to shock or vibration.
A device such as a contact breaker may be avibration source. Set the Power Supply as far as possible from possible sources of shock or vibration.
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 screws on the Power Supply

Installation and 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 wiring material to prevent smoking or ignition of wiring material caused by abnormal loads.

Notes:

1. The current rating per terminal of the output terminals is shown below. If the current exceeds the rating on a terminal, always use two terminals simultaneously.
  * S8FS-G015 to S8FS-G300: 20 A
  * S8FS-G600: 30 A
2. After completing the wiring, create the following clearance and creepage distance between the terminal wires and metal case.

Between any two of wires connected to the L, N and FG ( ) terminals and between wires connected to L, N terminals and the metal case: 6.4mm min.
Between any two of wires connected to the +V, -V and FG ( ) terminals and between wires connected to +V, -V terminals and the metal case: 3.2mm min.

Do not apply more than 150 N force to the terminal block when tightening it to avoid the terminal block damaged.
Be sure to remove the sheet covering the product for machining before power-on.

Output Voltage Adjustment

The output voltage adjuster (V.ADJ) may possibly be damaged. Do not add unnecessary power.
Do not exceed the rated output capacity and current after adjusting the output voltage.
Refer to the other Instructions Manual (3114994-5) for details on the optional models (S8FS-GE, S8FS-G-R, and S8FS-G-W).
Refer to the product datasheet for details.

Suitability for Use

Omron Companies shall not be responsible for conformity with any standards, codes or regulations which apply to the combination of the Product in the Buyer’ s application or use of the Product. At Buyer’ s request, Omron will provide applicable third party certification documents identifying ratings and limitations of use which apply to the Product. This information by itself is not sufficient for a complete determination of the suitability of the Product in combination with the end product, machine, system, or other application or use. Buyer shall be solely responsible for determining appropriateness of the particular Product with respect to Buyer’ s application, product or system. Buyer shall take application responsibility in all cases.

NEVER USE THE PRODUCT FOR AN APPLICATION INVOLVING SERIOUS RISK TO LIFE OR PROPERTY OR IN LARGE QUANTITIES WITHOUT ENSURING THAT THE SYSTEM AS A WHOLE HAS BEEN DESIGNED TO ADDRESS THE RISKS, AND THAT THE OMRON PRODUCT(S) IS PROPERLY RATED AND INSTALLED FOR THE INTENDED USE WITHIN THE OVERALL EQUIPMENT OR SYSTEM.

Precautions for Correct Use

Mounting

Standard mounting fig. 2
Standard Mounting on DIN Rail fig. 3
S8FS-GCD

When the screw holes provided on the chassis are used, the screws must not protrude more than 3 mm inside the Power Supply. If you must use screws that are longer than given above, refer to the product datasheet.
Tighten the mounting screws to the following torque:
M3 screws: 0.48 to 0.59 N·m
M4 screws: 1.08 to 1.32 N·m
Metal plate is strongly recommended as the mounting panel

Input Voltage Tolerance

Rating: 100 to 240 VAC

Mains supply tolerance for AC input: -10 to +10% (90 to 264 VAC)

Parallel Operation

This Power Supply is not designed for parallel operation. If you attempt parallel operation, overheating may damage internal parts.

Parallel operation is possible with the optional models (S8FS-G60024-W).

Output Voltage Adjustment

Default Setting: Set at the rated voltage

Adjustable Range: Adjustable with “V.ADJ ” ⑨ 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.

Note:
The output voltage may increase beyond the voltage adjustment range +15% or more when the V.ADJ adjuster ⑨ is used.
When adjusting the output voltage, check the output voltage of the Power Supply and be sure that the load is not destroyed.

Built-in fan (S8FS-G300, S8FS-G600) The built-in fan cannot be replaced.

Dielectric Strength Test

Rated dielectric strength:
3,000 VAC between < input terminals ① ② together > and < output terminals ④ ⑤ ⑥ ⑦ together > for 1 minute. When testing, set the cutoff current for the withstand voltage test device to 20 mA.

Notes:

If a tester switch is used to apply or cut off 3,000 V suddenly, the resulting impulse voltage may occasionally damage the Product.
When performing the test, be sure to short-circuit all the output terminals to protect them from damage.

Insulation Resistance Test

When testing the insulation resistance of the Power Supply, use a DC ohmmeter at 500 VDC.

Note: When performing the test, be sure to short-circuit all the output terminals to protect them from damage.

Overload Protection

The load and the Product are automatically protected from overcurrent damage by the overload protection function. When the current returns to within the rated range, the Product will automatically return to normal operation.

Notes:

Internal parts may possibly deteriorate or be damaged if a short-circuited, overload, or boost load state continues during operation.
Internal parts may possibly deteriorate or be damaged if the Product is used for applications with frequent inrush current or overloading at the load end. Do not use the Product for such applications.

Overvoltage Protection

This Product automatically protects itself and the load from overvoltage.
Overvoltage protection is activated if the output voltage rises above approx. 120% of the rated output voltage. To reset the Product, leave the Product 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 Product.

Overheat Protection

(S8FS-G300, S8FS-G600)

If the internal temperature rises excessively as a result of fan failure or any other reason, the overheat protection circuit will be triggered to protect internal elements. To reset the protection, turn OFF the input power for three minutes or longer and then turn it back ON.

Conformance to EU Directives

Refer to the catalogue and this instruction manual for details on the operating condition for EMC-compliance.
If you use the S8FS-G150 at 80% or more of the rated load, the harmonics standard will not be met. Do not connect the Product to a public power source when you operate it at 80% or more of the rated load.
