- The use of air filter in the air inlet of the control panel, especially in unclean and dusty areas
is mandatory, and the excessive dust inside the device will invalidate the warranty.
- Any direct and dense humidity (such as dew) can cause a lot of damage to the device and this
device will not be subject to warranty of replacement and repair.
The use of heaters inside the panel, especially in the winter, and wet environments, and places
where there is a potential for dew on surfaces, is mandatory, and in long term, it will result in
considerable savings on the maintenance and repair cost of electronic devices.
- The installation location temperature should be within the range -10 to +50 ° C and for the
temperature range of 40 to 50 ° C, the rated power should be reduced by 2% for per centigrade
increase in temperature. Temperatures outside this range will, not only significantly decrease
the lifetime of the device, but also invalidate its warranty.
The lifetime of the device's power capacitors will be halved for every 10 degrees being warmer
(in device's temperature) than the environment. So devices that operate in hot environments
or high-load environments, will be required their capacitor to be replaced in shorter time
intervals .
- The installation location should not be subjected to severe and consistent vibrations. If it is
necessary to install the device in such a place, consult with our company's experts before
installing it.
- Direct sunlight will dramatically decrease the lifetime of the device's box and keyboard, and
will also invalidate the warranty.
- If the altitude of the installation location is more than 1000 meters (above mean sea level),
you should consider 2% reduction in the power capacity of the device for every 100 meters more
height, otherwise there is a possibility of the device heating in the rated load. In this case, it is
required to have a device with larger power .
Note: Higher altitude (above mean sea level) as well as warmer environment, reduces the
lifetime of the power capacitors; because the air concentration decreases and the heat
exchange of the capacitors with the environment decreases in both situations.
