General
Perform megger
check
(between main
circuit terminals
and ground
terminal).

Disconnect I/O wires
from the inverter main
circuit terminal block
and remove the control
terminal block PCB.
Then, after removing
the short-circuit bar for
switching the inverter
built-in filter function,
measure using a
megger the resistance
between the ground
terminal and the
short-circuited terminals
