Check to ensure that the LED201 (Red) of the PCB2 is off.
1: 5 Screws (M5)
2: Fixing screw (M5)
Removing Transistor Module (IPM)
Disconnect all the wirings connected to the transistor module as shown below.
1 Remove PCB2 from IPM according to the procedure of “Removing Inverter PCB (PCB2)”.
2 Disconnect the wirings of P, N, U, V, W on the transistor module.
3 Remove four (4) M4 fixing screws on the transistor module.
4 Remove the transistor module from the electrical box.
5 Reassemble the parts in the reverse order of removing order.
1. Screws for PCB2 (M3)
2. Screw (M5)
3. Fixing screws for transistor module (M4)
4. Led201
5. Screws for PCB (M3)
6. CN207
7..CN026
8. CN2
Removing Capacitor for AC Fan Motor (CA)
1 Disconnect the wirings of capacitor for AC fan motor (CA).
2 Remove one (1) screw for fixing the capacitor and remove the capacitor
¿ Removing other electrical components
1 Remove the service cover following the Removing service cover, see on page 414.
2 Open the P-mounting plate by rotating 90 degrees to the left as show in the Opening electrical box (P-Mounting
Plate), see on page 423.
Check to ensure the LED201 (Red) of the inverter PCB (PCB2) is OFF when opening P-mounting plate.
N O T E
• Do NOT touch the electrical components when the LED201 (Red) is ON to avoid electrical shock.
3 Remove other electrical components according to the procedure below, and the figures are on the next page.
