n Insulation Caps or Sleeves
Use insulation caps or sleeves when wiring the drive with crimp terminals. Take particular care to ensure that the wiring does
not touch nearby terminals or the surrounding case.
n Insulation Barrier
Insulation barriers are packaged with drive models 4A0361 through 4A0590 to provide added protection between terminals.
Yaskawa recommends using the provided insulation barriers to ensure proper wiring. Refer to Figure i.5 for instructions on
placement of the insulation barriers.
