*1
When installing the inverter
board assembly, a cable tie
(Part number: NE43027-4,
Model: T-30R, Quantity: 1)
is required to attach the ring
core to the electrical fixing
plate.
*2
When replacing the inverter
board, handle it as the
“inverter board assembly”,
i.e., inverter board integrated
with heat sink.
Never replace the inverter
Board only. Replacement of the
inverter board only may cause
degradation of the radiation
performance of the heat sink,
leading to smoke or ignition.
*3 (AKZ56A only)
In order to remove the
screws on the inverter board
mounting plate, it is necessary
to remove the reactor.
