SMX1500RU2UNC - Outlet Groups Shutting Down

    Hello,

    I recently placed a brand-new SMX1500RU2UNC out on our factory floor over Labor Day weekend, but received a call this morning that it had shut down and had to be bypassed. I looked at the logs and found several messages of the following:

    09/11/2019 2:51:30 Device UPS: The output power is turned off. 0x0114

    The log configuration truncates at 400 messages (I have since changed this) so I couldn't see the very beginning of the issue, but looking at the power data readings it must have started within a 10-minute period:

    Date              Time         Vmin      Vmax     Vout       Iout      %Wout   %out     FrqOut    %Cap    Vbat      Tups
    09/11/2019    02:53:49   0.00       119.59    0.00       0.00     0.00        0.00      0.00        79.19     48.09    +33.63
    09/11/2019    02:43:49   115.59   118.78    117.38   1.69      51.47     13.87    60.02      79.19     49.28     +35.04
    09/11/2019    02:33:49   115.78   120.00    116.50   1.56     11.88      12.87    60.04      79.19     48.78     +34.99

    I have spoken with my maintenance about possible dirty power since I observed the following in the UPS logs:

    Number Date & Time Event Code Event
    1 09/11/2019 02:51:27.000 3 distorted input
    2 09/11/2019 02:51:18.000 3 distorted input
    3 09/11/2019 02:51:09.000 3 distorted input
    4 09/11/2019 02:50:59.000 3 distorted input

    My maintenance advised that if there were problems upstream with power that we would likely have seen issues in multiple areas, not just with the UPS. I understand the UPS may just be more sensitive to power fluctuations, but shouldn't the battery have kicked on instead of the power groups simply shutting down? Also, the power readings on the UPS showed they were within tolerance for normal sensitivity settings, but I'm not sure what course of action to pursue. I need some advice to understand if I have a faulty unit or if I just need to adjust some settings. Help would be much appreciated.
