For usage of the product for a long time
(1) Avoid using the product in an area with temperature or humidity exceeding specifications, or
subject to dew condensation.
When installing the product inside a panel, be sure that the temperature around the product (not the
temperature around the panel) is within the specification.
The life of parts depends upon the ambient temperature. Higher temperature decreases and lower
temperature increases the life of parts. Therefore, the life can be increased by lowering the inside
temperature of the digital panel meter.
(2) Use or store the product within the specified ambient temperature and humidity ranges.
If two or more products are installed close to each other or one is installed on top of another, the
inside temperature of the products may be elevated due to heat generation by products themselves,
resulting in decreased life of the products. In such cases, conduct forced cooling, for example, by
using a fan to ventilate the product.
(3) Since the life of output relay depends largely upon the capacity and condition of switching, be sure
to take the actual conditions of usage into consideration and to use it within the rated load and the
times of its electrical life.
Using it exceeding its life may cause welding of contact points or burning.
