American Power Conversion SYMSTRF3I user manual Environmental Requirements, Heat Output

Environmental Requirements

Install SymmetraTM in a temperature controlled, clean, dry, and protected indoor area that is free of conductive contaminants. The environment must have adequate airflow, and be free of corrosive fumes.

Environmental Condition	Acceptable Range
Temperature	32°F - 104°F (0°C - 40°C)
Relative Humidity	0 - 95% non-condensing
Elevation	0 to 10,000 feet above mean sea level (0 to 3,048 m)

Heat Output

Heat output of the SymmetraTM is significantly increased when batteries are charging. Battery recharge periods are relatively infrequent.

Short-Term Battery Module Storage Requirements

Battery modules must be temporarily stored until the electrical wiring is connected and the SymmetraTM is ready to be powered.

νBatteries should be stored at 0°F to 77°F (-18°C to 25°C) to preserve battery life.

νStorage environment can be within 0 to 100% relative humidity , non-condensing.Note: Condensation will cause corrosion of electronic and chassis parts.

Caution!

νInstalling battery modules in a SymmetraTM that is not powered will discharge the batteries and could damage them permanently. Do not install battery modules into the SymmetraTM frame until after the electrical wiring connections have been made, and the system is ready to be powered.
