• Identify the terminal numbers with mark band. When reassembling, the terminals have to be connected to the
correct numbers . If incorrectly connected, malfunctions or damages will occur.
• Check to ensure that the electrical wires will not be caught between the assembled electrical components and
the mounting plates when the PCB2 is reassembled.
¿ Removing diode module and transistor module
Check to ensure that the LED201 (Red) of the PCB2 is off.

1 Disconnect all the wirings connected to the diode module as shown below.
• Disconnect the wirings of the terminals +, - , U, V, W on the diode module.
• Remove the two (2) screws fixing the diode module.
• Remove the diode module from the electrical box.
2 Disconnect all the wirings connected to the transistor module as shown below.
• Disconnect the wirings of connector CN2, CN206 and CN207.
• Disconnect the wirings from P, N, U, V, W on the transistor module.
• Remove the three (3) screws fixing the PCB2 and then remove the PCB2 from the transistor module.
• Remove the four (4) fixing screws on the transistor module.
• Remove the transistor module from the electrical box.

• The correct position of the marks on the PCB2 is upside down when being assembled.
• Identify the terminal Nos. with the mark band Nos. when reassembling. If incorrectly connected, malfunction
or damage will occur.
• Check to ensure that the electrical wires will not be caught between the mounting electrical components and
the mounting plates when the PCB2 is remounted.
• Apply silicon grease evenly on the whole rear side of the diode module and the transistor module when
mounting. Silicon grease is available as a field-supplied accessory.
