Installation Instruction
  1. Connect pins 4 and 8 of the alternator to a single phase AC supply as shown in the installation diagram above.
  2. The hot side of the AC voltage is connected to one side of the control switch and pins 2 and 4 of the alternator. The opposite side of the control switch is connected to pin 6 of the alternator.
  3. One side of each contactor coil is connected to either pin 1 or 3 of the alternator depending upon the user preference for Lead/Lag designation.
  4. The opposite sides of the contactor coils are both connected to pin 8 of the alternator, the neutral side of the AC supply. Pins 9, 10 and 11 are wired in a similar manner.


Test Method

A single phase AC line and properly rated light bulbs are needed to test any alternator in the M.P.E. product line.

  1. The AC line and light bulbs must be connected to the alternator as shown in the test method diagram above.
  2. When the control switch is operated, the light bulbs will alternate on and off.
