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
