Galaxy PW™ UPS 100 to 225kVA

1.2General Description

The cabinets are cooled by forced ventilation. The air enters via the doors and grids at the bottom and is discharged through the roof, which means the cabinets can be positioned against the back wall.

Connections are made through the bottom. (Connections through the top are an available option.) The connection cables may be run in three ways:

◗In a trench running under the cabinets.

◗Under a false floor.

◗On the floor under the cabinets, in the free space equal to the height of the feet; in this case the cables should be run side by side to avoid blocking the flow of air for ventilation.

The cables for connections are between:

◗The battery and UPS cabinets (power and control cables).

◗The bypass AC-source transformer in an auxiliary cabinet and the UPS cabinet.

Only the wires for the inter cabinet control connections between parallel-connected UPS units are supplied.

The other power cables for connections between cabinets are not supplied.
