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
