Environmental Conditions
• Indoor use only.
• Maximum altitude: 6562 feet (2000 meters).
• 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 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.
