    Connecting Automatic Water Pump

    Hi,
    I have recently acquired an Automatic Water Pump Controller and I need to connect it to the water pump. On the circuit board, there is L, N and E which definitely connects to the mains.
    On the lower side I have E, U and V. My question is, can I power the water pump from these terminals labelled E, U and V?
    If this is the case, then between U and V which one is live or Neutral.
    Remember on the water pump there is already a power cable that I currently use to connect to the mains.

    Thanks Justloadit
    Just to clarify, currently I have the water pump, and it connects directly to the mains through a fused 3-pin 13 amp plug. Now I need to connect the water pump through the automatic pump controller which I have just acquired.
    So should I remove the 13 amp plug, then I connect the wires from the water pump (L, N and E) to the U, V and E on the pump controller directly?

    In that case the answer is - Yes. But ensure that the switch contacts are rated for your motor current.

    Hi, which of the 2 ( U &V) is live or neutral?

    On a single phase motor rated at 220v it would be immaterial and make no difference
    Generally U would be live
