Input Power Level
Operating Temperature
The temperature of the ECal module must be within the following temperature
range to meet the operating specifications.
— N755xA Series: +15 °C to +35 °C and up to 75% relative humidity (RH).
— N469xD Series: +20 °C to +26 °C and up to 95% relative humidity (RH) at
40 °C, non-condensing.
— N443xD Series: +20 °C to +26 °C and up to 95% relative humidity (RH) at
40 °C, non-condensing.
For more details, see
“Environmental Specifications” on page 5-2
