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.
