3.6 Main Circuit Wiring
This section describes the functions, specifications, and procedures required to safely and properly wire the main circuit
in the converter.
NOTICE: Do not solder the ends of wire connections to the converter. Soldered wiring connections can loosen over time. Improper
wiring practices could result in converter malfunction due to loose terminal connections.

◆ Protecting Main Circuit Terminals
■ Insulation Caps or Sleeves
Use insulation caps or sleeves when wiring the converter with crimp terminals. Take particular care to ensure that the
wiring does not touch nearby terminals or the surrounding case.
Insulation Barrier
■
Insulation barriers are packaged with models 4A0270 to 4A0630 to provide added protection between terminals.
Yaskawa recommends using the provided insulation barriers to ensure proper wiring. Refer to
Figure 3.26 for instructions on placement of the insulation barriers.
