Operating temperature

0°C to 45°C (32°F to 113°F) at an altitude of 0-1800 m (0-5906 ft.)

NOTE:

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.).

Short-term operating temperature

-5°C to +55°C (23°F to 131°F) at an altitude of 0-1800 m (0-5906 ft.)

NOTE:

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 equipment can operate beyond the normal operating temperature range for a short-term period, but the following conditions must be met:

• The equipment operates at a temperature of over 45°C (113°F) consecutively for at most 96 hours in one year.
• The equipment operates at a temperature of over 45°C (113°F) for a total of no more than 360 hours in one year.
• The equipment operates at a temperature of over 45°C (113°F) for no more in 15 times in one year.

The equipment cannot start when the temperature is lower than 0°C (32°F). The maximum distance of optical modules used in these conditions cannot exceed 10 km.

Storage temperature

-40°C to +70°C (-40°F to +158°F)
