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.

■ 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.
