Safety Precautions for All Digital Panel Indicators

Refer to the Precautions section for each Digital Panel Indicators for specific precautions applicable to each Digital Panel Indicators.

Precautions for Safe 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

Outdoor locations or 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. Heat generated by the product itself can raise its interior temperature and shorten its service life. Do not install multiple products side-by-side or stacked one on top of the other. If this kind of installation cannot be avoided, provide the products with forced cooling, such as that using fans.

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. Install each product on a designated panel of the recommended thickness.

8. When using crimp terminals or bare conductor connections, use the parts and materials that are designated for each model.

9. 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 shielded wires.

10.Make sure that the rated voltage is achieved within 2 s after turning ON the power.

11.Allow the product to warm up for at least 15 minutes after the power is turned ON.

12.Do not install the product near devices generating strong highfrequency 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 for cleaning.

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 specified supply voltage and rated load.

16.Do not connect anything to unused terminals.

17.Outputs turn OFF when the mode is changed or settings are initialized. Take this into consideration when setting up the control system.

18.Install and provide proper indications for a switch or circuit breaker that complies with the requirements of IEC 60947-1 and IEC 60947-3 to enable the operator to quickly turn OFF the power.

19.Provide a DeviceNet communications distance that satisfies the range given in the specifications, and use the designated communications cable. For cable details,refer to the DeviceNet Catalog (Cat. No. Q102).

20.Do not bend or pull the DeviceNet communications cable with excessive force.

21.Do not attach or remove connectors with the DeviceNet power turned ON. Doing so may cause product failure or malfunction.

22.Use wire that is capable of withstanding heat of 70°C min. to wire the K3HB series.
