Insulation Cap When you wire the main circuit terminals, do not let cable ends go near terminals or the drive. If you use crimped terminals, make sure that you also use insulation caps. Insulation Barrier Insulation barriers are packaged with drive models 4810 to 4H12 for additional protection between terminals. Use insulation barriers to make the wiring more reliable. Refer to Figure 1 for information about the insulation barrier installation procedure. Figure 1. Install the Insulation Barriers
