You may need to power cycle your UPS if you encounter a specific alarm (the FAQ specifying that alarm should direct you to this FAQ).  It is also recommended to power cycle your UPS prior to upgrading your UPS Firmware.  Depending on your system configuration, below are the proper steps in order to completely power cycle your UPS.

System Configuration: Service Bypass Unit (SBU) + UPS

1. Check the status of the UPS and follow the appropriate instructions below to get the UPS into bypass and the SBU switch in the proper position.
   
   1. UPS online:
      1. Command UPS into bypass. Home > Control > UPS > Put UPS in Bypass
   2. UPS online with alarm:
      1. Command UPS into bypass. Home > Control > UPS > Put UPS in Bypass
   3. UPS in fault bypass with alarm:
      1. UPS is already in the correct state
   4. UPS off with alarm: Reference System Configuration: UPS only System Power Cycle with Load Powered Off: section below.
2. Set the UPS Manual bypass switch to On
3. Set the SBU switch to bypass
   1. Note: The AC Mains is now connected directly to the load.  The UPS input and UPS output are not connected.
4. Set the System Enable switch on the back of the UPS to OFF.
5. Wait 2 minutes after complete system shutdown to ensure that the internal IM (Intelligence Module) power supplies are completely off.
6. Set the System Enable switch on the back of the UPS to ON.
7. Set the SBU switch to the Maintenance Position.
   1. Note:  The AC Mains is now connected directly to the load AND the UPS input.  The UPS output is not connected.
8. Wait approximately 3 minutes for both IMs (Intelligence Modules) to initialize.
9. Verify that the UPS has completely initialized by checking, via the display, that the IM firmware versions for both locations are populated and the same.
   
   1. Home > About > UPS > Intelligence Modules
10. Validate the only active warnings/Alarms are that the UPS is in Manual Bypass and the SBU switch is in the maintenance position.
    
    1. Note: If you are on NMC firmware version 2.x or 3.0 but < 3.3, and UPS firmware 15.0 or later, the display will show an alarm Unknown UPS internal error [1568-wxyz] - Later versions of NMC firmware will show a warning: The SBU switch is in the Test Position.
11. If other alarms or warnings are present, collect the debug logs. Contact Schneider Electric customer support.
12. Set the UPS manual bypass switch to off.
13. Perform functionality tests (optional).
    1. From Output Off turn the Output On.  Home > Control > UPS > Turn UPS On
    2. From Online, Put UPS in Bypass.  Home > Control > UPS > Put UPS in Bypass
    3. From Bypass, Return UPS from Bypass.  Home > Control > UPS > Return UPS from Bypass
    4. Perform UPS Self-Test. Home > Tests > UPS Self-Test
    5. Transfer UPS On Battery by setting the SBU Switch to BYPASS.
       1. Note: If you are on NMC firmware version 2.x or 3.0 but < 3.3, and UPS firmware > 15.0, the display will show Unknown UPS internal error [156A-wxyz] - Later NMC firmware versions will show a warning: The SBU switch is in the Bypass Position
    6. Transfer UPS from On Battery to online by setting the SBU Switch to Maintenance.
       1. Note: If you are on NMC firmware version 2.x or 3.0 but < 3.3, and UPS firmware > 15.0, the display will show Unknown UPS internal error [1568-wxyz] - Later NMC firmware versions will show a warning: The SBU switch is in the Test Position
    7. Observe which IM is acting MIM via the display or the lit led on the front of IM.  Typically, it is the IM in Location A but it could be location B.
    8. Perform IM handoff by loosening the thumbscrew of the acting MIM.
       1. Note: An alarm will appear for Invalid configuration, the Intelligence Module in Location A (or B), not installed.
    9. Retighten the IM thumbscrew
    10. Wait approx. 3 min for the power cycled IM to initialize.
    11. Repeat steps h, i, j for the IM that was not power cycled.
14. Ensure UPS output is on.  Home > Control > UPS > Turn UPS On
15. From Output On, Put UPS in Bypass. Home > Control > UPS > Put UPS in Bypass
16. Set the SBU Switch to Normal.
17. Verify the UPS is Online, and the load is reported correctly on the display.
18. End.

System Configuration: UPS only

System Power Cycle with Load Powered On:

1. Check the status of the UPS and follow the appropriate instructions below to get the UPS into bypass.
