10.16.2 Removing the PCB2 for the inverter
D A N G E R
• Turn OFF all the power source switches.
• Do
not
touch any electrical component if the LED201 (Red) of the PCB2 is ON. Touching them could cause an
electric shock.
1 Disconnect all the wiring connected to the PCB2 -A-.
2 Disconnect all the power supply lines of the transistor module
-E- (U, V, W) and direct the wiring from the current sensor. Also
disconnect the wiring for N, P and C.
3 Remove the three M3 screws -B-, remove the bushes -C- and
the collars -D- of the PCB2. When fitting the PCB2 make sure
that the bushes and the collars are well fixed.

• Match the
numbered terminals with the band marked with numbers when reassembling. 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.
10.16.3 Removing the diode module and transistor module
D A N G E R
• Turn OFF all the power source switches.
• Do
not
touch any electrical component if the LED201 (Red) of the PCB2 is ON. Touching them could cause an
electric shock.
