PROCEDURE FOR REPLACING ELECTRONIC BOARDS

The electronic boards are only to be replaced after the electrical power has been disconnected and a period of 10 minutes has
passed to enable complete discharge of the internal capacitors. Otherwise, this can pose a serious risk to the operator carrying
out the repair procedure.
Before replacing the electronic boards, make sure that the new parts correspond to the model of inverter to be repaired. Also check
compatibility of the software. If in any doubt, contact the manufacturer.
A) To access the electronic boards, remove the external cover, disconnect the power cables of the motor and any auxiliary inputs.
B) Unscrew the middle screw of the earth terminal and the six screws of the internal cover.
