See Sheet 6 of the wiring diagrams for connection details.
Follow EMC guidelines in the General Installation section.
Due to the RF voltages and currents generated by the drive causing conducted unwanted radio frequency
interference signals which by inductive/capacitive coupling can get into the supply network. It is important to pay
particular attention to the EMC guidelines.
Motor Encoder and Motor Data.
Details of the system available to TVC at time of panel manufacture, and used for programming of drive parameters,
are recorded on form TVF175 attached to the drive.
Ensure that the following parameters are set in accordance with the motor nameplate, encoder and lift mechanics.
If these details are incorrect, make sure parameters in the drive and Ethos Two match anything modified. e.g. motor
RPM etc. If any significant differences are found, contact TVC:

*It is important to note that if the motor current value exceeds the drive heavy duty value, then the current output will
be seriously reduced.
** If motor rated voltage is less than 300V please contact factory before an autotune is carried out.
Preliminary Work
Check all safety circuits and ensure all safety circuits are in order.
Ensure lift doors are closed and remain closed.
Switch to "Emergency Electrical Operation / Panel Test or Inspection Control / Car Top Test"
Power Up
Make sure the encoder type is correct for the application, Gear-less applications require specific encoders such as
one with an Hiperface or EnDat interface.
Check any external phase sequence inhibits and correct by reversing input phases if required.
