Wiring the Power supply to the unit into input number, one, via the "HI Z" terminals provides the benefit of measureing resistance to earth of this circuit.
...
Alternatively Inputs 4 and 5 can be wired directly across the terminal of each circuit to provide remote cell voltage monitoring. A wiring diagram showing such a solution is shown belowFULL FAT DIAGRAM
