Temperature compensation
NOTICE!
The temperature compensation offsets the charge cut-off voltage by the specified value per
battery cell (2 V cells in lead-acid batteries) and per degree Kelvin. For example, a temperature
coefficient of -4,0 mV/cell/K for a 48 V lead-acid battery causes the charge cut-off voltage to be
offset by -96 mV per degree Kelvin temperature difference relative to 25 °C.

NOTICE!
For lead-acid batteries, the system voltage always relates to the nominal voltage of the battery.
The device is configured for automatic voltage detection at the factory. This allows automatic
detection of the voltage levels 12 V, 24 V and 48 V. The system voltage must be directly
selected if the controller is to be used with system voltages of 36 V or 60 V. The system voltage
setting defines various other preset values and setting ranges.
