Thermal Site Considerations
In all but the coldest of climates, proper site selection can improve the life of the electronics and batteries in the field
cabinet. This can be done by:
• Reducing the field cabinet's exposure to the afternoon sun
Peak daily ambient temperature is generally attained between 2 p.m. and 3 p.m. The afternoon sun in combina-
tion with the high afternoon ambient temperature results in the maximum temperature rise inside of the field cab-
inet. Situating the field cabinet such that it is only exposed to the early morning and/or evening sun will reduce
the maximum temperature of the equipment and batteries inside of the field cabinet, thus extending their life.
• Increasing the field cabinet's exposure to wind
The greater the exposure to wind, the cooler the equipment inside will run, again extending equipment life. Solid
fences around the field cabinet are not desirable since they can block wind but not the overhead sun.
• Placing the field cabinet away from blacktop surfaces
Blacktop surfaces will collect and radiate heat onto the field cabinet. Grass or dirt provides a much cooler, more
favorable environment for the field cabinet.
Electrical Considerations
The availability of AC service, need for power meter, transfer switch, or generator inlet needs to be factored into the
site requirements. Refer to
service.
If a power pedestal is required, the size of the concrete pad may need to be larger to accommodate both the field
cabinet and the pedestal. As a result, the easement for the field cabinet may also need to be larger.
Safety
Whenever possible, a field cabinet should be located in vacant, unused, and out-of-sight portions of private, public,
or commercial property with easy access and adequate parking. If a field cabinet must be located near a street or
highway, it should be located away from curves and busy intersections.
