 Cleaning the contactors: In dirty environments (dust, sawdust, rust particles, etc.) vacuum
the contactor periodically.
There is no estimated time frame for cleaning, it depends on the amount of dirt that is inside the
capacitor bank.
5.2.4. KEY POINTS FOR INSPECTING CAPACITORS
 Inspect the cables and terminals. They should not be overheated or blackened.
 The terminals must be clean.
 The slow discharge resistors must be in good condition. They must not be open or show
signs of burning.

Check the tightness of the capacitor terminals, as shown in Table 5 .

5.2.5. KEY POINTS FOR INSPECTING THE REGULATOR
 Check that the regulator does not show signs of deterioration and the display is lit as normal.
 Inspect the cables and terminals. They should be clean and should not be hardened or over-
heated.

Inspect the connections and the insertion of removable power strips:
- The power strips must be well fastened on removable regulators.
- Check that the terminals are tightened properly. The recommended torque is 0.6 Nm.
