Normally DC BUS FAULT is fixed by replacing C14 and C10. C14 is the 100uf/63V and C10 is 2200uf/16V. They are located between the heat dissipator and the logic board near transformer TX1.

APC SURT3000XL UPS


The fault indicator means that there is a fault in the circuitry of the UPS. It could be the control board or another part of the system. (If the batteries were bad, you would see the Replace Battery light illuminate.) If the SURT3000XL is under warranty, contact APC. The standard warranty period is 2 years for repair/replacement. Note: you'll probably have to pay for the shipping of the unit. If the unit is out of warranty, replace it with a new UPS.

I hope this helps.

Mike Decamp is clueless. That is not a answer. The UPS has large DC capacitors. These do go bad over time. The capacitors are required to maintain a good DC Buss and helps in assisting when putting the UPS in bypass and back online. You can not turn on the inverter with out precharging the capacitors. Get the part numbers of the caps and replace. Make sure UPS and batteries are off or you will get shocked.

I have a Symmetra LX 16000 , and ups sen me the message ...Critical - UPS A main intelligence module fault exists.. code 0x0203.


Hi Scabcmx,

Without knowing the full model number of your UPS I cannot go into specific details fully for you.. but a good test with any 'intelligence module fault' is to re-seat the module and run a self test. If the fault remains then your intelligence module is bad and you will need to acquire a new one to replace the faulty one. This can all be done 'on-line' and you should not have any downtime... assuming there is a redundant intelligence module in the unit which is normally the case. This will clear the fault.

If you would like more information give me a call: 407.380.9200.

Symmetra LX16000,5.93kva; Problem;Alarm indicating power module fault.


Hi Akortic,



Without knowing the full model number of your UPS I cannot go into specific details fully for you.. but a good test with any 'power module fault' is to re-seat the module and run a self test. This only applies if you have an extra/redundant power module to support the load. If the fault remains then you have a bad power module and you will need to replace it as soon as possible. This can all be done 'on-line' and you should not have any downtime... assuming there is a redundant power module in the UPS. This will clear the fault.

If you would like more information give me a call: 407.380.9200.

Powerware 9120 DC Bus Fault Problem.


there is a 100uf/63v capacitor near the IRF630 fet. You need to replace this in order to fix this error. Along there is also a 2200uf/16v capacitor. It is a good idea to change the both at the same time.
