|
|
Short-term operating temperature |
-5°C to +50°C (23°F to 122°F) at an altitude of 0-1800 m (0-5905.44 ft.)
|
|
Restriction on the operating temperature variation rate |
When the altitude is 1800–5000 m (5906–16404 ft.), the highest operating temperature reduces by 1°C (1.8°F) every time the altitude increases by 220 m (722 ft.).
The device can work for a short period of time when the operating temperature is beyond the normal range, but the following conditions must be met:
- The operating temperature can exceed 45°C (113°F) for a maximum of 96 consecutive hours in a year.
- The total time when the operating temperature exceeds 45°C (113°F) in a year is less than or equal to 360 hours.
- The number of times the operating temperature exceeds 45°C (113°F) is less than or equal to 15 in one year.
If any of the preceding conditions is not met, the device may be damaged or an unknown error may occur.
Devices cannot start when the temperature is lower than 0°C (32°F). The maximum transmission distance of an optical module used for short-term operation cannot exceed 10 km.
