Space and Weight Considerations

The Power Array frame is 61cm (24") wide and 68.6cm (27") deep. Refer to table 4-1 for the height and weight of fully loaded systems.

Frame Size	Height	Weight
		Fully Loaded
MiniFrame	78.7 cm	238 kg
	31"	525 lb
MasterFrame	132.1 cm	419 kg
	52"	925 lb

Table 2-1 Height & Weight (Loaded w/ Modules)

Make sure there is adequate space and structural integrity to support the fully loaded frame. Refer to figure 2-1. The weight of the Power Array rests on four 3.8cm (1.5") diameter leveling feet. Positions of the leveling feet are shown. When installing the frame, allow 30.5cm (12") of clearance behind the frame for adequate airflow. (Air flows in through the front of the frame and out the back.) Allow 122cm (48") of clearance in the front of the SymmetraTM to access the PowerView and to install 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 that is free of conductive contaminants. The operating evironment must be clean, dry, and protected. The atmosphere must be free of dust and corrosive fumes. Adequate airflow must be provided for the operation of the system. Make sure environmental conditions are within the following parameters:

nRelative Humidity: 0 to 95%, non-condensing.

nTemperature: 0°C to 40°C (32°F to 104°F).

nElevation: 0m to 3,048m (0ft to 10,000ft).

nElectro-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 Power Array system. The BTU output is significantly higher while the batteries are charging. Under normal operating condi- tions, battery recharge periods are relatively infrequent.

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.
