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 (particularly 

sulfurizing gases, ammonia, etc.)

Locations subject to rapid temperature changes

Locations prone to icing and dew condensation

Locations subject to excessive vibration or shock

Locations subject to wind and rain

Locations subject to static electricity and noise

Habitats of 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.

Mount the product in the correct direction.

4.

Check terminal polarity when wiring and wire all connections 

correctly. The power supply terminals do not have polarity.

5.

Do not wire the input and output terminals incorrectly.

6.

Make sure the power supply voltage and loads are within the 

specifications and ratings for the product.

7.

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

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.

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.

Use a precision screwdriver or similar tool to adjust the setting 

knobs.

3.

Do not use the product in circuits with waveform distortion. Error 

will be large due to waveform distortion.

4.

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

control.

5.

To reduce the error in the setting knob, always turn the setting 

knob from the minimum setting toward the maximum setting.

6.

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

commercial alcohol.

Correct Mounting Direction, Mounting, 
and Removing

Mounting to DIN Track
1. Attach the product to the DIN Track with the tab at the top and 

the hooks at the bottom.

2. Push the product onto the Track until the hooks lock into place.

Removing from the DIN Track

Pull down on the bottom hook with a flat-blade screwdriver and lift 

up on the product.

Adjusting the Setting Knobs

Use a screwdriver to adjust the setting knobs. The knobs have a 
stopper that prevents them from turning beyond the full right or left 
position. Do not force a knob beyond these points.
