If the capacitance of the CML 110 should not suffice, then you can also switch
more than one CML 110 in parallel. However, here you must note that a max-
imum charging current of 2.4 A per CML 110 is to be expected at switch-on.
The full power of the 24 V power supply unit can only be used once all CMLs
have finished charging.
