CCR1016-12S-1S+ PSU for DC Redundant Supply

Hey guys,

Just a question in relation to the CCR1016-12S-1S+ PSU.
Is it possible to remove the second power supply and connect the pins to a din rail DC 24v 4A output supply?
I have the option of battery supply and would like to be able to use it with the CCR1016-12S-1S+ in case of mains power supply failure.

If so what kind of cable is best to use to connect the CCR1016-12S-1S+ to the din rail DC 24v 4A


Thanks in advance
