Problem    #1    The power indicator does not illuminate when the power is turned on. 

Cause

Inspection/Remedy/Adjustment

Replacement if a malfunction

1. Malfunction of voltage select 

harness *** 

For 200 V specifications   

a.  Check if there is a broken wire in the voltage 

select harness.

b.  Disconnect the connector at the transformer 

side, turn on the power and then measure the 
voltage at the cord. 
(The wiring position may vary depending on 
the voltage specifications.) 
OK if same as wall outlet voltage

  For 100V, 200V, 220 V specifications 

1)  OK if there is continuity between pins 

1-8, 2-8, 3-8, 4-8, 5-8 and 6-8 of the 
8-pin connector coming out from the 
transformer. [Fig. A] 

2)  OK if there is continuity between pins 

1-2, 3-4 and 5-6 of the 6-pin connector 
coming out from the transformer. 
[Fig. C] 

3)  OK if there is continuity between pins 

1-2 and 4-5 of the 5-pin connector 
coming out from the transformer. 
[Fig. D] 

•

  For 380V, 400V specifications 

1)  OK if there is continuity between pins 

1-3, 2-3 and 3-6 of the 6-pin connector 
coming out from the transformer. 
[Fig. B] 

2)  OK if there is continuity between pins 

1-2, 3-4 and 5-6 of the 6-pin connector 
coming out from the transformer. 
[Fig. C] 

3)  OK if there is continuity between pins 

1-2 and 4-5 of the 5-pin connector 
coming out from the transformer.
