INSTALLATION

This chapter introduces the installation and connection of NetSure 801 CAA series power supply system (power supply system for short).

Cabinet Installation

Cabinet Placement

Before installing and connecting the power system, make sure the layout of each cabinet in the power system, especially the placement of DC cabinet and rectifier cabinet. Different placement may directly impact the selection and installation of the parallel connection copper bars, there are mainly two placement modes:

Rectifier cabinet – DC cabinet spaced placement

The NetSure 801 CAA power supply system can be expanded up to 6000A. As the max current carrying capacity of single parallel connection bar is 2000A, when the system capacity exceeds

2000A, the system cabinets should be arranged in the way that the max current carrying capacity of one parallel connection bar does not exceed 2000A.

It is recommended to place the cabinets in the way of “Rectifier cabinet - DC cabinet- Rectifier cabinet- DC cabinet”. For a system composed of Rack1000-A rectifier cabinet, place one rectifier cabinet or two rectifier cabinets as a unit. For a system composed of Rack2000-A, Rack1500-A rectifier cabinet, place one rectifier cabinet as a unit.

Recommended arrangement of 6000A system using Rack1000-A rectifier cabinet.

Recommended arrangement of 6000A system using Rack2000-A, Rack1500-A rectifier cabinet:

Rectifier cabinet - Rectifier cabinet and DC cabinet - DC cabinet parallel placement

If the installation site does not permit the cabinet arrangement shown above, it is suggested to use two parallel connection copper bars so that the current carrying capacity of single connection bar does not exceed 2000A.

If ‘ Rectifier cabinet - Rectifier cabinet and DC cabinet - DC cabinet parallel placement ’ is adopted, the cabinet placement on the customer site must be stated or a schematic arrangement of the cabinets must be provided when pre-purchasing the power system.
