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.
