NOTE!

Danger due to non-observance of the permissible mains voltage tolerance.

This can cause malfunctions and damage.

► For the electrolyte circulation option, a restricted mains voltage tolerance vis-à-vis the

charger of 207 V to 250 V applies.

The electrolyte circulation option introduces air into the battery through capillary tubes that

are provided specifically for this purpose. This allows intensive mixing of the electrolyte to

take place. The benefit is the reduced heating of the battery, and consequently longer bat-

tery-life, plus reduced water loss during charging.

If a pump fault or leaks in the connection with the battery result in a fault being detected,

then the status code "Statecode 14" will appear on the display. One way in which this fault

can be indicated is by using an external indicator lamp to show a common error.
