MGE UPS Systems 12280 kVA user manual Maintenance, Check that there is no voltage on the terminals

6. MAINTENANCE

After installation, the CleanWave→ filter requires almost no maintenance.

We only recommend a periodic (e.g. annual) inspection.

This inspection must be done with no voltage by a qualified technician.

The working sequence is the following :

-Switch off the power of the CleanWave® filter.

-Open the housing in order to access the filter. In the case of the IP21 CleanWave® filter,

-Unscrew and remove the lower part of the front panel (see fig. 3 and 7).

-Check that there is no voltage on the terminals.

-Visually check the general aspect of the filter, especially that there is no excessive dust on the Lo and Zo chokes.

-If necessary, clean the Lo and Zo with compressed air or with a vacuum-cleaner.

-Check the tightening of the power terminals.

-Close the housing.

-Power up the filter.
