X3 - DC link bus The purpose of the DC link bus module is to supply the connected
module
inverters with the generated direct voltage.
Connectable cross-section: "Electro-plated copper" 3x10 mm, rounded

DANGER
The current carrying capacity of the copper bars is 120 A.
The 100 kW feeder supplies 230 A and would overload the copper
bars. It is therefore provided with 2 busbar connections with a current
carrying capacity of 120 A each. These take the power to busbars on
the right and left of the rectifier unit. The current distribution is not
monitored. Measures must therefore be taken at the planning stage to
ensure that the current fed to each busbar does not exceed the
specified maximum.
