When you insert wires or insert a flat-blade screwdriver into a release hole, do not press down on the terminal block with a force of 40 N or greater.
Do not wire anything to the release holes.
Do not tilt or twist a flat-blade screwdriver while it is inserted into a release hole on the terminal block. The terminal block may be damaged.
Insert a flat-blade screwdriver into the release holes at an angle. The terminal block may be damaged if you insert the screwdriver straight in.
Do not allow the flat-blade screwdriver to fall out while it is inserted into a release hole.
Do not bend a wire past its natural bending radius or pull on it with excessive force.
Doing so may cause the wire disconnection.
Do not insert more than one wire into each terminal insertion hole.
Do not pre-solder the ends of the wires. Doing so will inhibit proper connection.
If there is a possibility that the Unit will be subject to vibration or shock, use Wires with Ferrules or Stranded Wires.
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 if it is turned with unnecessary force. Do not turn the adjuster with excessive force. · After completing output voltage adjustment, be sure that the output power or output current does not exceed the rated output power or rated output current.

See the product catalog 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

For mounting types other than Fig. 2, refer to the catalog.

Input Voltage Tolerance

Rating:

100 to 240 VAC

Mains supply tolerance for AC input: -15 to +10% (85 to 264 VAC)
100 VAC with 100% load and 85 VAC with 85% load
When using an input voltage less than 100 VAC, reduce the load calculated with derating 1%/VAC.

Output Voltage Adjustment

Default Setting: Set at the rated voltage
Adjustment Range: The output voltage can be adjusted to between -10% to +16.7% of the rated voltage with the voltage output adjuster “V.ADJ” (⑬) on the front panel. (excluding the S8VK-X09024-EIP.)
Turning clockwise increases the output voltage, and turning counterclockwise decreases the output voltage.

Notes:
The output voltage may increase beyond the allowable voltage range when “V.ADJ” (⑬) operation is performed. When adjusting the output voltage, check the output voltage of the Product and be sure that the load is not destroyed.

Dielectric Strength Test

The Product is designed to withstand 3,000 VAC for one minute between input terminals ① to ④ together and output terminals ⑥ to ⑩ together. When conducting the test, 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 destroy the Product.
Increase/decrease test voltage gradually.
Be sure to short-circuit all the output terminals of the product to protect the product from damage.

Insulation Resistance Test

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

Note:
Be sure to short-circuit all the output terminals of the product to protect the product 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 shortcircuited, 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. 130% (110% on the S8VK-X09024-EIP only) 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.

Replacement Calculation Function

When the product is used in an application that involves frequent and repeated ON/OFF of the input voltage, the accuracy of the replacement calculation function and the total run time may be degraded.

Communications

Communications settings are required at installation or replacing the product. Set the settings correctly according to the communications manual.
For the EtherNet/IP or Modbus TCP connection method and the cables to be used, follow the information of the S8VK-X communications manual. Otherwise, communications may be faulty.
Do not exceed the communications distance that is given in the specifications.
If EtherNet/IP tag data links (cyclic communications) are used with a repeating hub, the communications load on the network will increase. This will increase collisions and may prevent stable communications.
Do not use repeating hubs on networks where tag data links are used. Use an Ethernet switch instead.
Do not pull on the communications cables or bend the cables beyond their natural limit. Do not place heavy objects on top of the communications cables or other wiring lines. Doing so may cause the wire to break.
To avoid inductive noise, keep the communications cables away from power cables carry high voltages or large currents. Also, do not wire power lines together with or parallel to product wiring.
If you do not connect the communications cable, always attach the dust cover.
Depending on the ambient temperature or load ratio, the Power Supply may get extremely hot.
In that case, minor burns may occur. Do not insert and remove communications cables.

Conformance to EU Directives

Refer to the catalog and this instruction manual for details on the operating condition for compliance with the EMC Directive.

Connecting Wires to the Push-In Plus Terminal Block

Part Names of the Terminal Block
Connecting Wires with Ferrules and Solid Wires Insert the solid wire or ferrule straight into the terminal block until the end strikes the terminal block.
If a wire is difficult to connect because it is too thin, use a flat-blade screwdriver in the same way as when connecting stranded wire.

Connecting Stranded Wires

Use the following procedure to connect the wires to the terminal block.

Hold a flat-blade screwdriver at an angle and insert it into the release hole.
The angle should be between 10° and 15°.
If the flat-blade screwdriver is inserted correctly, you will feel the spring in the release hole.
With the flat-blade screwdriver still inserted into the release hole, insert the wire into the terminal hole until it strikes the terminal block.
Remove the flat-blade screwdriver from the release hole.

Checking Connections

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.
If you use a ferrule with a conductor length of 10 mm, part of the conductor may be visible after the ferrule is inserted into the terminal block, but the product insulation distance will still be satisfied.

Removing Wires from Push-In Plus Terminal Block

Use the following procedure to remove wires from the terminal block.
The same method is used to remove stranded wires, solid wires, and ferrules.

Hold a flat-blade screwdriver at an angle and insert it into the release hole.
With the flat-blade screwdriver still inserted into the release hole, remove the wire from the terminal insertion hole.
Remove the flat-blade screwdriver from the release hole.

Recommended Flat-blade Screwdriver

Use a flat-blade screwdriver to connect and remove wires.
Use the flat-blade screwdriver shown at right.
