11.02 Verification and Remedy to the Indicated Error Codes 

 

Note 

The capacitors inside the power supply will slowly discharged after you turn off the switch 
of the power supply or the switch at the breaker box (distribution panel).  Wait at least 5 
minutes for the discharge to complete and then remove the cases to continue your 
inspection and repair (or maintenance) inside the power supply. As for the removal and 
installation of the case, refer to section 11.01.1. 

 

Note 

During the “

Verification/Remedy

” procedures below, follow the alphabetical sequence (a, b, 

c…) and proceed with your verification and confirmation. 

 

Note 

After you Verify and replace all spare parts and components, Verify that there are no 
damaged harnesses or connectors, uninstalled or loose screws.
