21 Maintenance
Only little maintenance is required to keep your inverter and system operating reliable. The inverter must be
switched off during maintenance and/or repair activities. It also must be secured against unexpected and uninten-
tional switching on. Therefore switch off the connection between batteries and inverter and be sure that third
parties cannot reverse the measures taken.
The following Steps must be undertaken at least once a year. Check cable and wires for damage and if they are
still firmly connected. Defects such as loose connections ore damaged cables etc. must be corrected immediately.
Keep the inverter dry, clean it from dust in order to ensure good heat discharge.
