Space and Weight Considerations

All Power Array frames are 24” wide and 27” deep. Refer to table 4-1 for dimensions and weights of fully loaded systems.

Table 2-1Power Array Dimensions and Weights (Fully

Loaded with Modules)

Make sure there is adequate space and structural integrity to support the fully loaded frame. Refer to figure 2-1 below. The weight of the Power Array rests on four 1.5” diameter leveling feet. Positions of the leveling feet are shown. When installing the frame, allow 12” of clearance behind the frame for ad- equate airflow. (The fans on the system pull air in through the front of the frame, and blows it out the back.) Allow 48” of clearance in the front of the SymmetraTM to access the PowerView interface, and for installation and replacement of modules.

Transporting Power Array to Installation Site

When it is shipped, the Power Array frame is bolted to a cus- tom-designed pallet. The modules are stacked on either one or two additional pallets. It is recommended that these pallets be moved from the receiving dock to the installation area with a pallet jack. Make sure there is enough space and structural integrity to move these pallets.

Operating Conditions

The Power Array is intended for installation in a temperature- controlled, indoor area, free of conductive contaminants. The operating evironment must be clean, dry and protected. The atmosphere must be free of dust and corrosive fumes. Ad- equate airflow must be provided for the operation of the sys- tem. Make sure environmental conditions where the SymmetraTM is to be installed are within the following param- eters:

νOperating Relative Humidity: The Power Array will op- erate within a relative humidity range of 0 to 95%, non- condensing.

νOperating Temperature: The Power Array will operate within a temperature range of 32°F to 104°F (0°C to 40°C).

νOperating Elevation: The Power Array will operate at elevations within a range of 0ft to 10,000ft (0m to 3,048m).

νElectro-Static Discharge (ESD) Susceptibility: The Power Array and all modules are capable of withstanding “through air” electro-static discharges up to an ampli- tude of +/-15kV and “direct discharge” electro-static dis- charges up to an amplitude of +/-8kV without failure, abnormal operation or degradation in performance. ESD test methods conform to IEC 801-2.

BTU Output

Refer to table 2-2 for BTU output of a fully loaded, and func- tioning Power Array system. The BTU output is significantly higher while the batteries are charging. Under normal operat- ing conditions, battery recharge periods are relatively infre- quent.

Table 2-2 BTU Output

Temporary Storage of Modules

The battery and power modules must be temporarily stored until the frame is permanently installed. To preserve battery life, always store batteries in a cool, dry place.
