NetSure 801 CA7 Power Supply System (New Skelecton) User Manual
3.1.5 Installation Of System Above 2000A
The NetSure 801 CA7 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 Rack1000-7 rectifier cabinet, place one rectifier cabinet or two rectifier cabinets as a unit.
For a system composed of Rack2000-7 rectifier cabinet, place one rectifier cabinet as a unit.
Recommended arrangement of 6000A system using Rack1000-7 rectifier cabinet:

If the installation site does not permit the cabinet arrangement shown above, it is suggested to use 2 parallel
connection copper bars so that the current carrying capacity of single connection bar does not exceed 2000A. When
using 2 connection bars, only external parallel connection can be used and the connection bars must be specially
made.
3.1.6 Mounting Large Side Door And Small Side Door
The rectifier cabinet and distribution cabinet have two side doors on both sides, as shown in Figure 3-7. According to
distribution situation, cabinet placement and cabinet parallel connection, the side doors are configured in various
ways.
Prior to cabinet parallel connection, check that there is at least one large side door between adjacent cabinets. The
large side doors of the rectifier cabinet and the distribution cabinet are interchangeable. Users can exchange them on
the spot.
