Storage temperature[°C(°F)] | –40°C to +70°C (–40°F to +158°F) |
Short-term operating temperature[°C(°F)] | -5°C to +50°C (23°F to 122°F) at an altitude of 0-1800 m (0-5905.44 ft.) |
Long-term operating temperature[°C(°F)] | –5°C to +45°C (23°F to 113°F) at an altitude of 0 to 1800 m (0 to 5905.44 ft.) |
Restriction on the operating temperature variation rate[°C(°F)] | 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 exceeds 45°C (113°F) for no more than 96 consecutive hours in a year. - The total time in which the operating temperature exceeds 45°C (113°F) in a year is less than or equal to 360 hours. |
