General characteristics of Galaxy 5000 UPSs
INFORMATION The operating temperature range is 32°F to 104°F (0°C to +40°C); for overload
conditions is 32°F to 86°F (0°C to +30°C). Optimum operating range is within 68°F
to 77°F (20°C to +25°C). Battery backup time is adversely affected by high and low
temperatures. It is significantly reduced at temperatures under 50°F (10°C). Above
77°F (25°C), battery service life is cut in half every 18°F (10°C). Above 104°F (40°C),
battery manufacturers no longer guarantee operation due to the risk of thermal
runaway.
