5.2.4. KEY POINTS FOR INSPECTING STATIC SWITCHES
 Check that the plastic parts are not blackened and do not show signs of burning or hardening.
 Check that the head is properly inserted.
 Check the tightness of cables and terminals, as shown in Table 6 .

Thyristor type Power cable connection torque (Nm)
IXYS 3.25
 The terminals must be clean.
 Cleaning: In dirty environments (dust, sawdust, metal trimmings, etc.). Vacuum the dust and
solid remains regularly.
There is no estimated time frame for cleaning, it depends on the amount of dirt that penetrates
the cabinet of the capacitor bank.
5.2.5. 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 7 .

5.2.6. 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.

Check the connections and the insertion of removable power strips, if used:
- The power strips must be well fastened on removable regulators.
- Check that the terminals are tightened properly. The recommended torque is 0.6 Nm.
5.2.7. CLEANING THE CABINET
 Remove any solid particles.
 Clean the inside of the cabinet.
 Clean ventilation grilles.
