Precautions for Safe Use

Suitability for Use

1)    Do not use the product in the following locations.

Locations subject to direct radiant heat from heating 

equipment

Locations where the product may come into contact 

with water or oil

Locations subject to direct sunlight

Locations where dust or corrosive gases (in 

particular, sulfuric or ammonia gas) are present

Locations subject to extreme temperature changes

Locations where icing or condensation may occur

Locations subject to excessive shocks or vibration

2)

Do not use the product in locations subject to temperatures 
or humidity levels outside the specified ranges or in 
locations prone to condensation. If the product is installed 
in a panel, ensure that the temperature around the product 
(not the temperature around the panel) does not go outside 
the specified range. 

3)

Provide sufficient space around the product for heat 
dissipation.

4)

Use and store the product within the specified 
temperature and humidity ranges. If several products 
are mounted side-by-side or arranged in a vertical line, 
the heat dissipation will cause the internal temperature 
of the products to rise, shortening the service life. If 
necessary, cool the productss using a fan or other 
cooling method. 

5)

The service life of the output relays depends on the 
switching capacity and switching conditions. 
Consider the actual application conditions and use the 
product within the rated load and electrical service life. 
Using the product beyond its service life may result in 
contact welding or burning.

6)

Install the product horizontally.

7)

Mount to a panel between 1 and 8-mm thick.

8)

Use the specified size of crimp terminals (M3, width: 
5.8 mm max.) for wiring. To connect bare wires, use 
AWG22 to AWG14 to wire the power supply terminals 
and AWG28 to AWG16 for other terminals. 
(Length of exposed wire: 6 to 8 mm) 

9)

In order to prevent inductive noise, wire the lines 
connected to the product separately from power lines 
carrying high voltages or currents. Do not wire in 
parallel with or in the same cable as power lines. 
Other measures for reducing noise include running lines 
along separate ducts and using shield lines.

10) Ensure that the rated voltage is achieved no longer than 

2 s after turning the power ON.

11) Allow the product to operate without load for at least 15 

minutes after the power is turned ON.

12) Do not install the product near devices generating 

strong high-frequency waves or surges. When using a 
noise filter, check the voltage and current and install it 
as close to the product as possible.

13) Do not use thinner to clean the product. 

Use commercially available alcohol.

14) Be sure to confirm the name and polarity for each 

terminal before wiring the terminal block and connectors

.15) Use the product within the noted supply volage and 

rated load. 

16) Do not connect anything to unused terminals.
17) Output turns OFF when the mode is changed or 

settings are initialized. Take this into consideration 
when setting up the control system. 

18) Install an external circuit breaker or switch that 

conforms to IEC60947-1 and IEC60947-3 requirements 
and label them clearly so that the operator can quickly 
turn OFF the power.

19) Use the specified cables for the communications lines 

and stay within the specified DeviceNet 
communications distances. Refer to the User's Manual 
(Cat. No. N129) for details on communications distance 
specifications and cables. 

20) Do not pull the DeviceNet communications cables with 

excessive force or bend them past their natural bending 
radius. 

21) Do not connect or remove connectors while the 

DeviceNet power is being supplied. Doing so will cause 
product failure or malfunction. 

For detailed application procedures, refer to the Digital 
Indicator K3HB-S, X, V, H User's Manual
 (Cat. No. N128). 
For details on using communications functions, refer to the 
Digital Indicator K3HB Communications User's Manual (Cat. 
No. N129).
