VI
● Extending Product Life
(1) 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.
The service life of internal components depends on the ambient temperature. The higher
the temperature is, the shorter the service life will be. Therefore, the product's service life
can be extended by keeping the product interior at a low temperature.
(2) Use and store the product within the specified temperature and humidity ranges.
If several Linear Sensor Indicators are mounted side-by-side or arranged in a vertical
line, the heat dissipation will cause the internal temperature of the Linear Sensor
Indicators to rise, shortening the service life. In this case, cool the Linear Sensor
Indicators using a fan or some other method.
(3) 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.
(4) Do not use thinner to clean the product. Use commercially available alcohol.
