Parts Layout On The Outdoor Unit Inverter Pcb - Mitsubishi Heavy Industries FDTCVA SERIES Technical Manual

Parts layout on the outdoor unit inverter PCB

Model FDCVA302HENR
Notes (1) Apply the silicone grease supplied with the component uniformly to the surface of the power transistor on the new PCB, then mount it on the PCB. If the grease
is not applied, the power transistor may be damaged. Use all the silicone grease.
(2) Tighten the power transistor mounting screws of the inverter PCB, and connect the terminal block, faston terminals and connectors. After connection, make sure
tightening was not forgotten and parts were not partially inserted only. In particular, make sure the power transistor is not loose by tightening the mounting
screws securely. If they are not tightened, the power transistor may be damaged.
