Planning the electrical installation

Implementing a bypass connection
If bypassing is required, employ mechanically or electrically interlocked contactors
between the motor and the drive and between the motor and the power line. Ensure
with interlocking that the contactors cannot be closed simultaneously.
WARNING! Never connect the supply power to the drive output terminals U2, V2
and W2. Line voltage applied to the output can result in permanent damage to the
unit.
Example bypass connection
An example bypass connection is shown below.
Switching the motor power supply from drive to direct-on-line
1. Stop the drive and the motor with the drive control panel (drive in local control
mode) or the external stop signal (drive in remote control mode).
2. Open the main contactor of the drive with S11.
