7.6.7 Wiring Alternating Master<br />
Fig. 43 and Fig. 44 show the relay functions<br />
MasterPump1-6 and SlavePump1-6. The Master and<br />
Additional contactors also interlock with each other to<br />
prevent dual powering of the pump and damage to<br />
the <strong>inverter</strong>. (K1M/K1S, K2M/K2S, K3M/K3S). Before<br />
running, the <strong>SX</strong>-V will select a pump to be Master,<br />
depending on the pump run times.<br />
CAUTION: The wiring for the Alternating<br />
Master control needs special attention and<br />
! should be wired exactly as described here,<br />
to avoid destructive short circuit at the output of the<br />
<strong>inverter</strong>.<br />
