The voltage inputs are reverse phased, requiring phase swapping to correct. The manual's first action is: “If this is the initial start up, swap any two of the leads connected to "L1", "L2", or "L3" on the Motor Mentor to correct the problem. If the overload relay has been previously running, the power system has been reverse phased. Check the phase sequence of the incoming power lines. Note: "L1" must be tapped from conductor Phase A, "L2" from B, and "L3" from C for correct power factor measurements on remote communications.”

What to do
- If this is the initial start up, swap any two of the leads connected to "L1", "L2", or "L3" on the Motor Mentor to correct the problem. If the overload relay has been previously running, the power system has been reverse phased. Check the phase sequence of the incoming power lines.
