For details, it is recommended contact our Schneider Electric service centre to help ensure correct functioning of the installation and maintenance.
After 6 to 12 months of operations, we recommend to check the busbars and MV cable connection tightening.
-
Check the power connections like busbars, cable connections and fixed contacts with a calibrated torque spanner.
-
Compare the values indicated and adjust if required. Refer to Screw Fastenings.
The elastic washers placed on the external sides of the connections and busbars helps to ensure better distribution of stress induced by the screw torque.
If no problems are detected, the busbars and cable connections are not modified, it is not necessary to do again this check. In case of dismantling, discard the removed elastic washers and install new elastic washers supplied by Schneider Electric.
