Maintenance

8.1

Disposal of waste electronic equipment

Waste electronic equipment must not be disposed of as unsorted municipal waste, e.g.

household waste. When disposing of waste electronic equipment, the current local national/

international regulations must be observed.

Maintenance

Disregarding the following measures may result in severe operation failures, bursting and fire.

• Check tightness of the connections/terminals periodically, two weeks after installation at

• Clean the terminals / bushings periodically to avoid short circuits due dust or other

• Check the short circuit protection fuses.

• Take current reading twice a year and compare with nominal current. Use a harmonic

• In case of a current above the nominal current check your application for modifications.

• If a significant increase in the amount of non-linear loads is detected, a consultant has to be

• In cases of the presence of harmonics, the installation of a de-tuned capacitor bank

• Check the discharge resistors / reactors and in case of doubt check their function:

1. Power the capacitor up and down.

2. After 60 seconds the voltage between the terminals must decline to less than 75 V. Please

• Check the temperature of energized capacitors. In case of excessive temperature of
