3.8 Main Circuit Wiring
This section describes the functions, specifications, and procedures required to safely and properly wire the main circuit
in the drive.
NOTICE: Do not solder the ends of wire connections to the drive. Soldered wiring connections can loosen over time. Improper wiring
practices could result in drive malfunction due to loose terminal connections.
NOTICE: Do not switch the drive input to start or stop the motor. Frequently switching the drive on and off shortens the lifetime of the
DC bus charge circuit and the DC bus capacitors, and can cause premature drive failures. For the full performance life, refrain from
switching the drive on and off more than once every 30 minutes.

◆ Protecting Main Circuit Terminals
■ Insulation Cap
Use insulation caps when wiring the drive with crimp terminals. Take particular care to ensure that wiring does not touch
neighboring terminals or the surrounding case.
■
Insulation Barrier
Insulation barriers are packaged with drive model CIMR-E4A0414 through 4A1200 to provide added protection
between terminals. Yaskawa recommends using the insulation barriers provided to ensure proper wiring. See Figure 3.19
for instructions on where the insulation barriers should be placed.
