1.5 Pump Wiring Diagramm
The following two figures describe the general wiring of the single phase and three phase electric pumps.
Single phase Three phase
At wiring, electric pumps should be correctly installed with electrical leakage protector, and a yellow-green wire attached
with earthing mark in the outgoing cable of electric pump shall be earthed reliably. For electric pumps provided with plug
at delivery, the matched patch board must be reliably earthed. Matched overload protection devices shall be selected by
current or power for all electric pumps. The wiring of electric pumps can be carried out according to the figure below.
2-pole: 2.2~11kW electric pump 2-pole: 15~22kW electric pump
4-pole: 11~22kW electric pump
2-pole: 15~22kW thermal protector
4-pole: 11~22kW thermal protector
