19 Maintenance and Care
19.1 Housing
Check that every housing of the Sunny Backup System S is mechanically sound. If damage (e.g.
cracks, holes, missing covers) endangers the operating safety, the Sunny Backup 2200 must be
deactivated immediately.
Larger particles of dirt should be removed from the device with a soft brush, or similar object. Dust can
be removed with a damp cloth. Solvents, abrasives or corrosive materials must not be used for
cleaning!
19.2 Device Display
19.3 Sunny Remote Control 1
Clean the control elements with a soft, damp cloth. Solvents, abrasives or corrosive materials must not
be used for cleaning!
19.4 Function Testing
Check regularly whether error messages are present. If an error message is displayed for which you
cannot identify any apparent cause, the backup system must be inspected by an installer. To ensure
optimal operation, the operator should regularly check the entries in the Sunny Backup 2200 error
list at short intervals (monthly, or even weekly), especially during the first months after commissioning.
This can help to discover hidden faults in the installation or errors in the configuration.
Check that the Sunny Backup System S functions properly at least once a year. Thus, the Sunny
Backup 2200, the Automatic Switch Box S, and the battery are tested for correct functionality. Despite
the available grid, you can start the backup operation using the "530.02 BkupTst" function
implemented in the Sunny Backup 2200.

Unintentionally starting the Sunny Backup 2200 when cleaning the membrane

NOTICE!
Unintentionally starting the device when cleaning the button by accidentally

Checking the ground connection
Once a year, visually inspect the ground connection at the house connection box, or on
the meter board between PEN and the equipotential bonding bar!
