Issue:
My Smart-UPS will not turn on.
Product Line:
Smart-UPS
Environment:
All models except SURT, All Serial Numbers
Cause:
1) The Battery is disconnected
2) The input breaker is off
3) There is no Input Power, or it is of poor quality
Resolution:
1) The Battery is disconnected:
2) The input breaker is off - Smart-UPS greater than 1500VA have an input breaker which must be in the ON position in order to operate. It is usually located on the rear panel, next to the input power cord. If this breaker is in the OFF position, the UPS will not actually see the input current and will not turn on.
3) There is no Input Power, or it is of poor quality - The UPS will not turn on if the input power is outside of the parameters for online operation. To determine if the issue lies with the input power or with the UPS itself, you can ""Cold Start"" the UPS. This performs a self-test and forces it up on battery power.
To perform a cold start:
If the cold start is successful: You have determined that the UPS is functional and can operate on battery without issue. You can now plug the UPS into the wall. If it still does not come online you can adjust voltage transfer points and/or sensitivity levels to allow the UPS to function with the available power. On an SU, SUA, or SUM unit this can be accomplished via software or the Network Management Card. On an SMC, SMT or SMX unit this can also be performed via the LCD screen. If the input power is of such low quality that you are unable to adjust the UPS to function online you should consult an electrician or your utility provider.

Cause:
1) The Battery is disconnected
2) The input breaker is off
3) There is no Input Power, or it is of poor quality
Resolution:
1) The Battery is disconnected:
- SC, SU, and SUA Smart-UPS require a functional battery be connected in order to turn on. If the battery is disconnected, or failed and completely drained, the UPS will not turn on.
- SMX, SMT, SRT, and SMC series Smart-UPS do not typically have this limitation, however a deeply discharged battery may still be an issue. Try disconnecting the battery.
- SURT series Smart-UPS require that internal batteries are connected and capable of supporting a load in order for the UPS to turn on. Each battery in a 208v Smart-UPS SURT (10kva or less) must measure more than approximately 85volts and each battery in a 120v Smart-UPS SURT must measure greater than approximately 42volts. Smart-UPS SURT units do not charge while in bypass operation and leaving a unit in bypass for extended periods of time can cause batteries to drop below these thresholds. Once batteries have dropped below these points they will need to be replaced.
2) The input breaker is off - Smart-UPS greater than 1500VA have an input breaker which must be in the ON position in order to operate. It is usually located on the rear panel, next to the input power cord. If this breaker is in the OFF position, the UPS will not actually see the input current and will not turn on.

To determine if the issue lies with the input power or with the UPS itself, you can ""Cold Start"" the UPS. This performs a self-test and forces it up on battery power.
To perform a cold start:
- Unplug the Smart-UPS from the wall
- Press and hold the power button (labeled I/Test on SU and SUA units)
- Let go of the button during the long beep
- UPS will cycle through a self test and come up on battery
If the cold start is successful: You have determined that the UPS is functional and can operate on battery without issue. You can now plug the UPS into the wall. If it still does not come online you can adjust voltage transfer points and/or sensitivity levels to allow the UPS to function with the available power. On an SU, SUA, or SUM unit this can be accomplished via software or the Network Management Card. On an SMC, SMT or SMX unit this can also be performed via the LCD screen. If the input power is of such low quality that you are unable to adjust the UPS to function online you should consult an electrician or your utility provider.
If the cold start is unsuccessful or the unit displays a fault code: Your unit likely has a hardware issue. Contact the Customer Care Center for further assistance.
