3.2.5 Placing DC Cabinet Separate From System
The NetSure801 power supply system uses integrated monitoring, the DC distribution cabinet can be placed separate
from the system, and typically where loads are grouped, for example, on different floors. When connecting the DC
distribution cabinet to the system, use cable to connect between the parallel connection bars. Pay attention to the
following points:
Use cable rather than copper bar to connect between the parallel connection copper bars of the DC distribution
cabinet and the system to ensure accurate measurement of load current. The connecting points are the
installation holes for parallel connection copper bar.
Communication inside the system uses CAN mode.
3.3 Connecting Power Cables
Note
Before electrical connection, turn off all of the switches and fuses.
The accessory cables used in cable connection are given in Table 3-1.
