Ambient
temperature
Minimum temperature: 0°C, Maximum temperature: 40°C The average temperature
over any 24-hour period must be in the range 5 to 35°C.
3 Relative humidity
The relative humidity must be held between 30 and 90%. There must be no
condensation due to temperature changes.
4 Altitude
This equipment must not be applied at altitudes that exceed 1000m (3240 ft) above
seal level.

Vibration and
mechanical shock
Vibrations in the installation environment must have frequencies either lower than
10 Hz, or higher than 20 Hz.
For vibrations under 10 Hz, the acceleration due to those vibrations must not
exceed 0.5 G.
For vibrations over 20 Hz and under 50 Hz, the acceleration due to those vibrations
must not exceed 0.5 G.
For vibrations over 50 Hz and under 100 Hz, the total amplitude must not exceed
0.1 mm.
6 Dust
Dust in the room where the UPS is installed must not exceed normal atmospheric
dust levels. In particular, that dust must not include iron particles, oils or fats, or
organic materials such as silicone.
