Altitude and Air Pressure
At altitudes above 5,000 feet (1,525 meters), the maximum short-term temperature limit 
reduces by 1o Fahrenheit for each 1,000 feet (305 meters) of elevation above 5,000 feet 
(1,525 meters). For example: at sea level, the maximum short-term temperature limit is 
120
o F (49o Celsius). At 10,000 feet (3,050 meters), the...

Air Purity
The Compact Modular Cabinet, Single-Carrier and Multi-Carrier Cabinets contain an air 
filter to reduce particulates flowing through the equipment. Do not install the cabinet 
where the air may be contaminated by excessive dust, lint, carbon particles, paper fiber 
contaminants, or metallic contaminants. For example, do not install the...

45 Environmental Considerations 
Small tools with universal motors are generally not a problem when they operate on 
separate power lines. Motors without commutators generally do not cause interference. 
Field strengths below 1.0 volt per meter are unlikely to cause interference. 
Measure weak fields with a tunable meter. Measure field strengths greater than 1.0 volt 
per meter...
