Operating temperature |
-5°C to +45°C (23°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.). |
The switch cannot be started when the ambient temperature is lower than 0°C (32°F). |
