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.
