Dc And Ac Busbars; Stator Side Connection Procedure - ABB ACS800 Series Hardware Manual

DC and AC busbars

• Short circuit the L-shaped DC busbars of the converter modules.
• Short circuit the L-shaped AC busbars of the LCL filter module.
• Measure the insulation resistances between the DC busbars and the converter
frame and between the AC busbars and the converter frame by using a
measuring voltage of 1 kV DC. The insulation resistance must be higher than 1
Mohm.

Stator side connection procedure

The stator connections are located in the stator section of the power cabinet.
• Read and repeat the steps in
• Open the stator section door of the power cabinet.
• Remove the protective covers from lower part of the cabinet.
• Lead the cables through gland into the cabinet.
• Cut the cables to suitable length
• Strip the cables
• Crimp the cable lugs.
