Troubleshooting
NO
Check
for power
supply voltage.
Voltage between
phases: 460V ± 10%
or 208/230V
± 10%.
NO
YES
Onsite causes.
Make proper wire
connections
without open
phase, erroneous
connections, or
erroneous order
of phases.
Unbalanced
power supply?
(Not more than 2%:
Phase voltage of not
more than
approx. 5V)
NO
YES
Onsite causes
Correct the
unbalanced
loads to eliminate
the unbalanced
state.
Unbalanced
voltage will
cause extremely
unbalanced
current, thus
impairing the
service life of or
resulting in the
defective the
equipment.
The
insulation
resistance is low (i.e.,
not more than
100k
Ω
.)
YES
Replace the
compressor.
For 230V units:
(1) Does the power supply
voltage fall in the
range of 230V±10%?
(2) Is there any open
phase or erroneous
wiring in the power
supply line?
(3) Is an imbalance in
power supply voltage
not more than 6V?
Disconnect the cable from
the compressor, and then
check the compressor for
the insulation resistance.
A
Caution
Be sure to turn off the power switch before
connecting or disconnecting connectors, or parts
may be damaged.
