| Long-term operating temperature [°C(°F)] | -5°C to +45°C (23°F to 113°F) at an altitude of 0-1800 m (0-5906
ft.) |
| Short-term operating temperature [°C(°F)] | -5°C to +50°C (23°F to 122°F) at an altitude of 0-1800 m (0-5906
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 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. |
| Storage temperature [°C(°F)] | -40°C to +70°C (-40°F to +158°F) |
