Instruction Manual 12
•
Keep the capacitor terminals and reactors clean.
•
Verify the state of the contactors of operating elements.
•
Check that the capacitor current is not less than 25% or greater than 120% of the nominal
value by phase and that there is no phase unbalance greater than 15%.
Annually
•
Perform dielectric rigidity tests on the different elements of the power circuit, applying 2.5 kV
during 1s between the capacitor and earth terminals.
•
Check the capacity of the different steps. An indirect verification can be performed by checking
that the consumption matches the value stated in Table 7.5, with a maximum deviation of ±
10%.
•
Check the tightness of all terminal connections on the different power elements.
•
Inspection of the fuses.
-
Power circuit: NH fuses. Check continuity and temperature.
- Control Circuit protection: Neozed fuses or circuit breaker. Check continuity and
temperature.
7.2.2 Tightening the electrical connections.
•
The connections must be tight. The following tightening torques for the fuse bases and
contactors are listed in tables 7-1 and 7-2
