Instruction Manual 11
• Once ensured that the regulator is properly connected, adjust the regulator parameters for the
installation you are attempting to compensate. For this, follow the regulator's instructions
manual included with the battery.
6.3 Checkings once the filter bank is connected and the regulator has been adjusted
• After start-up, make sure that the equipment is operating correctly. A sign of proper operation
after the regulator's reaction time has passed is a cosϕ near to 1. In addition, the reactive
meter must stop.
• Check that the power supply voltage does not exceed the nominal value +10% (IEC 60831-1)
• Check the current absorbed by each LC group of the filter. Under normal working conditions, it
must be close to the nominal values (see Table 7.5) and never more than 1.3 times this value
continuously. Continuous consumption over the nominal value may be caused by the
presence of harmonics in the grid or an excessively high power supply voltage. Both
circumstances are harmful for capacitors and the filter's reactors.
• In accordance with the IEC 60831-1 Standard, the capacitor is prepared to operate at the
permanent voltage assigned and with an overvoltage of up to 10% during 8 hours every 24
hours.
• NOTE: For filter banks, the capacitor's voltage exceeds the grid voltage by a % that is
approximately equal to the filter's overvoltage factor (p%). In fact, the capacitor's real
overvoltage is

Check the working temperature of the capacitors and reactors after they
have been operating for 24 hours. The capacitor capsule must be under
40ºC. The housing of reactors can reach temperatures of about 60ºC

MAINTENANCE
7.1 Safety regulation
SAFETY
Apply the safety regulations listed in section 2 of this manual before operating the
equipment.
The standards and applicable national regulations of the country where the filter
bank is installed or operated should be strictly followed.
7.2 Maintenance with the filter bank disconnected
7.2.1 Basic maintenance protocol
Monthly
• Visually inspect the capacitors
• Check the protection fuses
• Control the environmental temperature (average of 30 ºC. In accordance with IEC 60831 ).
• Control the service voltage (especially during moments of low charge, it must not exceed the
nominal +10%).
