Visual Inspection:-
During visual inspection the overall condition of the inverter installation should be checked for following points:
-Mechanical damages of the housing
-Traces of oxidation caused by humidity, aggressive gases, or liquids
-Dust sedimentation inside the inverter, especially conductive dust
-Dirt and dust sedimentation on the heat sink and the motor terminal board
-Damages of cable isolation (especially at the inverter lead-through)
-Traces of humidity and water inside the cubicle

Checks:
-Perform the following checks:
-Take the actual parameter settings and compare them with the commissioning settings
-Check of the electrical plug connections (connection correct and fixed) and check connector pins for oxidations
-Check the conditions of the enclosure gaskets
