BAS-311G, BAS-326G
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
