Wiring 2-wire loads to the voltage output of non-isolated module
Wire the loads to the Q
V
terminals and to the reference point of measuring circuit M
ANA
.
Interconnect terminal S+ to Q
V
with terminal S to M
ANA
in the front connector.
A 2-wire circuit does not provide for compensation of line impedance.
