1.

 Do not use or store the product in the following locations.

Locations subject to water, or oil

Outdoor locations or under direct sunlight

Locations subject to dust or corrosive gases (sulfurizing gases, 

ammonia gases, etc.)

Locations subject to rapid temperature changes

Locations prone to icing and dew condensation

Locations subject to vibration and large shocks

Locations subject to wind and rain

Locations subject to static electricity or noise

Locations subject to insects or small animals

2.

Use and store the product in a location where the ambient 

temperature and humidity are within the specified ranges. If 

applicable, provide forced cooling.

3.

Check terminal polarity and wire all terminals correctly. The power 

supply terminals, however, do not have polarity.

4.

Do not wire the input and output terminals incorrectly.

5.

Make sure the power supply voltage and loads are within the 

specifications and ratings for the product.

6.

Make sure the ferrule terminals for wiring are of the specified size.

7.

The stripping length is 8 mm. Insert the wires all the way to the 

back.

8.

Do not connect anything to terminals that are not being used.

9.

Use a power supply that will reach the rated voltage within 1 

second after the power is turned ON.

10.

Keep wiring separate from high voltages and power lines that draw 

large currents. Do not place product wiring in parallel with or in the 

same path as high-voltage or high-current lines.

11.

Do not install the product near equipment that generates high 

frequencies or surges.

12.

The product may cause incoming radio wave interference. Do not 

use the product near radio wave receivers.

13.

Install an external switch or circuit breaker and label it clearly so 

that the operator can quickly turn OFF the power supply.

14.

Make sure the indicators operate correctly. Depending on the 

application environment, the indicators may deteriorate 

prematurely and become difficult to see.

15.

Do not use the product if it is accidentally dropped. The internal 

components may be damaged.

16.

Be sure you understand the contents of this catalog and handle 

the product according to the instructions provided.

17.

Do not install the product in any way that would place a load on it.

18.

When discarding the product, properly dispose of it as industrial 

waste.

19.

When using the product, remember that the power supply 

terminals carry a high voltage.

20.

The product must be handled only by trained electrician.

21.

Prior to operation, check the wiring before you supply power to the 

product.

22.

Do not install the product immediately next to heat sources.

23.

Perform periodic maintenance.

24.

Do not wire anything to the release holes.

25.

When you insert a flat-blade screwdriver into a release hole, do not 

tilt or twist the screwdriver. The terminal block may be damaged.

26.

Insert a flat-blade screwdriver into the release holes at an angle. 

The terminal block may be damaged if the screwdriver is inserted 

straight in.

27.

Do not allow the flat-blade screwdriver to fall when you are holding 

it in a release hole.

28.

Do not bend a wire past its natural bending radius or pull in it with 

excessive force. Doing so may break the wires.

29.

Do not insert more than one wire into each terminal insertion hole.

30.

To prevent wiring materials from smoking or igniting, confirm wire 

ratings and use the wiring materials given in the following table.

31.

Use only the specified wires for wiring.

32.

When wiring the terminals, allow some leeway in the wire length.

33.

Make sure that the power supply is turned OFF before you change 

any DIP switch setting.

Observe the following operating methods to 
prevent failure and malfunction.

1.

Use the power supply voltage, input power, and other power 

supplies and converters with suitable capacities and rated outputs.

2.

The distortion in the input waveform must be 30% max. If the input 

waveform is distorted beyond this level, it may cause unnecessary 

operation.

3.

Error will be large if the product is used for thyristor or inverter 

control.

4.

When cleaning the product, do not use thinners or solvents. Use 

commercial alcohol.

5.

If you use stranded wires, make sure that there are no loose wire 

strands.

6.

If you wire crossovers and connect terminal blocks in parallel, a 

large current will flow. Make sure that the current does not exceed 

10 A.

7.

The terminal block may be damaged if the recommended tool is 

not used. Use the recommended flat-blade screwdriver to operate 

the release holes.

Correct Mounting Direction, Mounting, and 
Removing

Mounting to DIN Track

To mount the Relay to a DIN Track, hook the Relay onto the DIN 
Track and press the Relay in the direction of the arrow until you hear 
it lock into place.

Removing from the DIN Track

To remove the Relay, insert a screwdriver into the hook on the top or 
bottom and pull out the hook to release the Relay.

• Leave at least 30 mm of space between the product and other 

devices to allow easy installation and removal.
