Measure line voltage
between Inverter main
circuit terminals R/L1,
S/L2, and T/L3.
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
R/L1, S/L2, T/L3, U/T1,
V/T2, W/T3, P/+2, +1,
N/–, and RB.
Retighten loose bolts
and screws.
Perform visual
inspection.
