Continuous
operation
When operating in the expanded temperature range, system performance may be impacted,
and ambient temperature warnings may be reported on the LCD and in the System Event Log.
≤ 10% of annual operating hours: 5°C to 10°C and 35°C to 40°C (with no direct sunlight on
the equipment) at 5% to 85% relative humidity with 26°C dew point (maximum wet bulb
temperature). Outside the standard operating temperature (10°C to 35°C), the system can
operate down to 5°C or up to 40°C for a maximum of 10% of its annual operating hours. For
temperatures between 35°C and 40°C (95°F to 104°F), de-rate maximum allowable dry bulb
temperature by 1°C per 175m above 950m (1°F per 319 ft above 3117 ft).
≤ 1% of annual operating hours: –5°C to 5°C and 40°C to 45°C (with no direct sunlight on
the equipment) at 5% to 90% relative humidity with 26°C dew point (maximum wet bulb
temperature). Outside the standard operating temperature (10°C to 35°C), the system can
operate down to –5°C or up to 45°C for a maximum of 1% of its annual operating hours. For
temperatures between 40°C and 45°C (104°F to 113°F), de-rate maximum allowable dry bulb
temperature by 1°C per 125m above 950m (1°F per 228 ft above 3117 ft).
Expanded operation restrictions:
• No cold startup below 5°C
• Maximum altitude for the operating temperature must be 3050m (10,000ft)
Expanded
operation
