Power Cable Busbars
A view of power cable busbars of large ACx 600 units is shown below. 
If necessary, the same screw can be used for connecting two cable 
lugs (on both sides of 
the busbar). Cable lugs with one or two holes 
can be used. 
Always use a torque wrench for tightening the busbar 
connections. Note: In inverter modules R6i and R7i, only one cable lug 
can be connected to a busbar screw.
