2.3 Environmental
Considerations
Many industrial environments create severe operating conditions. The conditions at each EAM location
must be within the specifications stated in section 6.
CAUTION
Exceeding the specified operating temperature limits can adversely affect
performance and may cause damage. Air temperature should be
periodically checked to ensure that this specification is not being
exceeded.
To ensure reliable data communications, it would be prudent to locate APACS modules (enclosures) as
far as possible from sources of interference such as high current electrical equipment which emit strong
electromagnetic fields and switching transients.
Industrial environments often contain particulate, liquid, and gaseous contaminants. Particulate matter,
usually dust and dirt, is abrasive and can cause intermittent contact in connectors associated with circuit
assemblies. A layer of dust on circuit boards will interfere with semiconductor heat dissipation. Liquid
and gaseous contaminants can have a corrosive effect on metal, rubber, plastic and circuit board
components. Extended exposure to this environment may result in equipment malfunction.
To reduce contaminant related equipment malfunctions:
4. Identify contaminants and implement methods to reduce their presence.
2. When cleaning equipment and surrounding area, especially the floor, either vacuum away all dust and
dirt or use a dampened rag or mop.
3. Clean or replace all air conditioning filters, room air filters, and equipment filters regularly. Inform
personnel with access to APACS modules of the need for area cleanliness.
