Environmental Conditions
• Indoor use only.
• Maximum altitude: 10,000 feet (3,048 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.
