How to use the bus bar
• Screw the top and bottom bus bar alternately starting from the converter unit side.
• Overlap and screw the bus bar on the TE2 terminal block of the drive unit.
• If the number of drive units connected to the converter unit is an even number, there will be a gap between
the TE2 terminal block of the drive unit at the far end and the bus bar by the thickness of the conductor.
Insert the adjustment bar (MR-DCBAR024-B05) between the TE2 terminal block and the bus bar and screw
it in.
Connect L+ and L- of the converter unit and L+ and L- of the drive unit using the dedicated bus bar as follows. The figure is
drawn with the terminal cover removed.
When connecting multiple drive units to the converter unit, arrange them in descending order of capacity per axis of the drive
unit from the right side of the converter unit.
