5.2.2. TIGHTENING TORQUE OF THE ELECTRICAL CONNECTIONS

The connections must be tight.

The tightening torques for the fuse bases are indicated in Table 2.

Table 2:Torques for the power cables of the three-pole circuit breakers.

5.2.3. 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 3.

 The terminals must be clean.

 Cleaning: In dirty environments (dust, sawdust, metal trimmings, etc.). Vacuum the dust and

solid waste regularly.

There is no estimated time frame for cleaning, it depends on the amount of dirt that penetrates

the cabinet of the capacitor bank.

5.2.4. KEY POINTS FOR INSPECTING CAPACITORS

Inspect the cables and terminals. They should not be overheated or blackened.

 The terminals must be clean.

 Check the tightness of the capacitor terminals, as shown in Table 4.

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.

Check the connections.

Check that the terminals are tightened properly. The recommended torque is 0.6 Nm.
