6. Set charge terminating voltage
1. The power supply must have reached operating temper-
ature.
For this purpose it must be operated for at least two hours at
rated load and with closed housing.
2. Connect a
A not completely charged accumulator leads to a miss-
alignment.
3. Adjust the voltage at the accumulator terminals using the
potentiometer PO3 according to the ambient temperature at
the accumulator as per the following table.
Only alter the charge terminating voltage:
1. After measuring the exact temperature and
2. When the voltage deviates >200 mV from the set value as
per following table.
