Standard operating temperature
Specifications
Continuous operation (for altitude less than 950 m or
3117 ft)
10°C to 35°C (50°F to 95°F) with no direct sunlight on the
equipment.
Expanded operating temperature
Table 24. Expanded operating temperature specifications
Expanded operating temperature
Specifications
Continuous operation
5°C to 40°C at 5% to 85% RH with 29°C dew point.
NOTE:
Outside the standard operating temperature (10°C to
35°C), the system can operate continuously in temperatures as low
as 5°C and as high as 40°C.
For temperatures between 35°C and 40°C, de-rate maximum
allowable temperature by 1°C per 175 m above 950 m (1°F per 319 ft).
≤ 1% of annual operating hours
–5°C to 45°C at 5% to 90% RH with 29°C dew point.
NOTE:
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,de-rate maximum allowable
temperature by 1°C per 125 m above 950 m (1°F per 228 ft).
NOTE:
When operating in the expanded temperature range, system performance may be impacted.
NOTE:
When operating in the expanded temperature range, ambient temperature warnings maybe reported in the System
Event Log.

Particulate and gaseous contamination specifications
The following table defines the limitations that help avoid any equipment damage or failure from particulate and gaseous
contamination. If the levels of particulate or gaseous pollution exceed the specified limitations and result in equipment damage
or failure, you may need to rectify the environmental conditions. Remediation of environmental conditions is the responsibility of
the customer.
