Inverter Analyzer Check
Check No.15
Characteristics
Inverter analyzer: RSUK0917C
If an abnormal stop occurs due to compressor startup failure or overcurrent output when using
an inverter unit, it is difficult to judge whether the stop is caused by the compressor failure or
some other failure (main PCB, power module, etc.). The inverter analyzer makes it possible to
judge the cause of trouble easily and securely. (Connect an inverter analyzer as a quasi-
compressor instead of compressor and check the output of the inverter)
Operation Method
Step 1
Be sure to turn the power off.
Step 2
Install an inverter analyzer instead of a compressor.
Note:
Make sure the charged voltage of the built-in smoothing electrolytic capacitor drops to 10
VDC or below before carrying out the service work.
Reference:
If the terminals of the compressor are not FASTON terminals (difficult to remove the wire on
the terminals), it is possible to connect wires available on site to the outdoor unit from output
side of PCB. (Do not connect them to the compressor at the same time, otherwise it may
result in incorrect detection.)
Step 3
<35/50 class>
Activate the power transistor test operation from the outdoor unit.
1) Press the forced cooling operation [ON/OFF] switch for 5 seconds.
(Refer to page 104 for the position.)
→
Power transistor test operation starts.
(R18322)
(1) Remove the terminals from
the compressor.
(2) Connect the terminals to the
terminals of the inverter
analyzer.

Be careful not to let the terminals (U,V,W)
touch each other. Otherwise, high voltage
is applied.
