Guidelines Concerning Solar Panels
All of Luna iMonitoring’s sensor modules and iCCUs employ a single, solar-assisted
battery for power. Properly orienting the solar panels on the WEMS component
achieves a maximum battery life of more than two years. Place the component
in a non-shaded area with the solar panels facing toward the sun. Also, ensure
that the site chosen will not become shaded due to tree growth or installation of
other structures.
Guidelines Concerning Hazardous Environments
Luna iMonitoring sensor modules mount directly onto structures such as a tanks,
pipelines, or wellheads located in hazardous areas. These sensor modules (iEFM,
iTLM-1, and iWPM-T) are, by design, intrinsically safe and meet the standard for
UL-913 certification for Class I, Division 1, Groups C and D hazardous areas. By
definition, an intrinsically safe apparatus is one in which all the circuits are
intrinsically safe; and an intrinsically safe circuit is one in which any spark or
thermal effect is incapable of causing ignition of a mixture of flammable or
combustible material in air under prescribed test conditions, according to the
National Electrical Code.
The iCCU mounts onto structures outside the hazardous zones in the oil field;
for example, an area greater than 3 meters from an oil tank.
