1. Check if power, grounding, and control connections are correct and firmly secured.
2. Remove from inside the inverter or the cabinet all the materials left behind from the installation work.
3. Verify the motor connections and if its voltage and current are within the inverter rated values.
4. Mechanically uncouple the motor from the load:
If the motor cannot be uncoupled, make sure that any speed direction (forward or reverse) will not result in
personnel injury and/or equipment damage.
5. Close the inverter or cabinet covers.
