ENVIRONMENTAL
CONDITIONS
Environmental Conditions
 Maximum altitude: 9843 feet (3000 meters).
 Ambient temperature range: -30° to 130°F (-34° to 54°C).
 Main supply voltage fluctuations not to exceed ±10% of the
nominal voltage.
 Transient over-voltages according to Installation Categories
II (Over-voltage 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.
