5% RH to 85% RH, non-condensing

Short-term operation

5% RH to 95% RH, non-condensing

Storage relative humidity

0% RH to 95% RH, non-condensing

Long-term operation altitude

Less than 3,000 m (9842.4 ft)

Storage altitude

Less than 5,000 m (16404 ft)

NOTE:
  • The measurement point of the temperature and humidity is 1.5 m (4.92 ft) above the floor and 0.4 m (1.31 ft) from the front of a cabinet. Before measuring temperature and humidity, remove the protection panels at the front or back of the cabinet.
  • Short-term operation means that the continuous working time does not exceed 96 hours and the accumulated time per year does not exceed 15 days.
Take the following measures to ensure that the preceding requirements can be met:
