Appendix C: Specifications
Product Service 1-800-522-7658 62
Environmental Conditions
• Indoor use only.
• Maximum altitude: 12000 feet (3657 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 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.
