Environmental Conditions 
•  Indoor use only. 
•  Ambient temperature range: 41° to 104°F (5° to 40°C). 
•  Maximum relative humidity: 80% for temperatures up to 88°F 
(31°C), decreasing linearly to 50% relative humidity at 104°F (40°C). 
•  Main supply voltage fluctuations not to exceed ±10% of the nominal 
voltage. 
•  Transient overvoltages according to Installation Categories II 
(Overvoltage Categories per IEC 1010). Temporary voltage spikes on 
the AC input line that may be as high as 1500V for 115V models and 
2500V for 230V models are allowed. 
•  Used in an environment of Pollution degrees 2 (i.e., where normally 
only non-conductive atmospheres are present). Occasionally, 
however, a temporary conductivity caused by condensation must be 
expected, in accordance with IEC 664.
