7. Connect the new gate drive wires to the terminals on the inverter IGBT with the correct polarity,
as follows. Do not use the old gate drive wires on the new inverter IGBT.
a. For the gate wires on the left, connect the black wire to the left terminal (6 or G2) and the
red wire to the right terminal (7 or E2).
b. For the gate drive wires on the right, connect the black wire to the left terminal (5 or E1) and
the red wire to the right terminal (4 or G1).
c. Make sure that the gate drive wire connectors are fully installed on the terminals. Use needle
