6.2 Installation Environment and Installation Position
6.2.1 Installation environment
(1) Installation location
Do not install the A/D converter module in places where:
• Ambient temperature is outside the range of 0 to 55;
• Ambient humidity is outside the range of 5 to 95% RH;
• Condensation occurs due to rapid temperature change;
• Corrosive gas or combustible gas is present;
• There are a high level of conductive powder such as dust and iron powder, oil mist, salinity, or organic
solvent;
• It is exposed to direct sunlight;
• A strong electric field or strong magnetic field is generated; and
• The module is subject to vibration and shock.
(2) Installation surface
Install the A/D converter module on a flat surface. Unevenness on the installation surface causes application of
an excessive force to the printed-circuit board, which may lead to a malfunction.
6.2.2 Installation position
When installing the A/D converter module in a control panel, provide a clearance of at least 60mm from the
surroundings including adjacent structures and modules to ensure good ventilation and easy module change.
