Question
How do you wire the KM20 Power Sensor and how do you mount the Current Transformer (CT)?
Answer
The CT has specific wiring and the Power Sensor has polarity (see Figure 1).
Wire the CT so that the load side of the sensing line is on the side of the CT with the label "L" and the power supply for the sensing line is on the side of the CT with the label "K."
Be sure that K and L are connected correctly (see Figure. 2).
If the polarity is incorrect, the power indicator (POWER, green) will flash (see Figure. 3).
