Plus. Run
a wire from the L1 OUT terminal to the other in-line controls such as pressure or float switches.
3. Connect the other line from the fused disconnect (ungrounded fused conductor) to the L2 IN
terminal of the PumpSaver
®
Plus. Run a wire from the L2 OUT terminal to the other in-line
controls such as pressure or float switches (see Figure 1).
