5.7Environmental Characteristics

The operating temperature is 0 to 40°C (8 hours at 45°C), however optimum operation is within the +20 to +25°C range and at 5-95% humidity, non-condensing at altitude up to 3280ft without de-rating.

The storage temperature : -20 to 40°C. Humidity : 5-95%, non condensing.

Battery backup time is adversely affected by high and low temperatures. It is significantly reduced at tempera- tures under 10°C. Above 25°C, battery service life is cut in half every 10°C. Above 40°C, battery manufacturers no longer guarantee operation due to the risk of thermal runaway.

Air enters through the front air vent grills and exits through the back. Always keep air vent grills unobstructed.
