CLEANING THE CABINET
Remove possible metallic and non-metallic particles.
Clean the inside of the cabinet.
Clean ventilation grilles.
5.3.- MAINTENANCE WITH THE CAPACITOR BANK CONNECTED
Check that the main switch turns on and off without having to force the mechanism.
If there is an individual earth leakage protection for the capacitor bank, check its proper
operation by pressing the test button.
Check that the auxiliary control voltage is within the tolerance limits.
If the capacitor bank has an autotransformer, check that it is in good condition and shows no
signs of deterioration.
Force the connection and disconnection of the capacitors in manual mode. (refer to the reg-
ulator's manual before carrying out these actions) and perform the following checks:
- Check that the contactors connect and disconnect properly.
- Check that the contactor, once connected, does not rattle or vibrate.
- Check the consumption of the capacitors in each of the phases.
The nominal values are shown in
.

Note:
If consumption is
±
25% less than that indicated in
and the voltage is within the
tolerance limits, this is usually a sign of degradation of the capacitors. If this is detected in any
capacitor, it should be replaced with another capacitor.
