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.

The terminal blocks may heat up to 65

°

C. Use care when 

handling them.

16.

Do not use the product if it is accidentally dropped. The internal 
components may be damaged.

17.

Be sure you understand the contents of this catalog and handle 
the product according to the instructions provided.

18.

19.

When discarding the product, properly dispose of it as industrial 
waste.

20.

When using the product, remember that the power supply 
terminals carry a high voltage.

21.

The product must be handled only by trained electrician.

22.

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

23.

Do not install the product immediately next to heat sources.

24.

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.

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.
