N O T E
•
The correct position of the PCB2 and the transistor module are shown in the figure.
•
Match the numbered terminals with the band marked with numbers when reassembling them. If they are
connected incorrectly, this may cause a malfunction and damage the electrical components.
•
Check to ensure that the electrical wiring does not get caught between the electrical components and the
mounting plate when you fit the PCB2.
•
Lightly apply conductive silicone grease (service parts No. P22760) on the whole rear side of the transistor
module (IPM) and diode module (DM) when mounting.
