2-wire connection of loads to a voltage output of a non-isolated module
Wire the loads to the Q
V
terminals and to the reference point of measuring circuit M
ANA
.
Connect terminal S+ to Q
V
and terminal S to M
ANA
in the front connector.
On the 2-conductor connection, the line resistances are not compensated.
