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
