SETTINGS
6.1.4 Battery type
The factory setting for the battery type is optimal for most installations. In some cases it is still desirable to change this setting.
Adjust the Mass Combi to the applied batteries by adjusting DIP switches SW6 and SW7. Wrong adjustment can cause
damage to your batteries which is not covered by the warranty.
The setting for traction battery should never be used with a battery bank that consists of 2V GEL cells!
