7.2.3 Key points for inspecting contactors.
•
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 7-2
•
The terminals must be clean.
•
If the filter bank includes RD discharge resistances, check they are in good condition (that they
are not open or show signs of burning).
Fig. 7-1 .- Connection of the discharge resistances
•
Cleaning the contactors: In dirty environments (dust, sawdust, metal trimmings, etc).
Periodically vacuum the dust and solid remains. There is no estimated time frame for cleaning,
it depends on the amount of dirt that penetrates the filter bank's cabinet.
