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.
