u Main Input Circuit and Motor Wiring
This section outlines the various steps, precautions, and checkpoints for wiring the main circuit terminals and motor terminals.
WARNING! Electrical Shock Hazard. Do not connect the AC power line to the bypass output terminals. Failure to comply could result in
death or serious injury by fire as a result of bypass damage from line voltage application to output terminals.
NOTICE: Route motor leads U/T1, V/T2, and W/T3 separate from all other leads to reduce possible interference related issues. Failure to
comply may result in abnormal operation of drive and nearby equipment.
NOTICE: When connecting the motor to the output terminals T1, T2, and T3, the phase order for the drive and motor should match. Failure
to comply with proper wiring practices may cause the motor to run in reverse if the phase order is backward.
NOTICE: Do not connect phase-advancing capacitors or LC/RC noise filters to the output circuits. Failure to comply could result in damage
to the drive, phase-advancing capacitors, LC/RC noise filters or ground fault circuit interrupters.
