What does it mean when my Riello MSM 10 displays A39 or A40 and the battery replacement LED is on?
If the Riello UPS display shows one or more of the following codes: A39, A40, and the red “batteries to be replaced” LED is on, it indicates that the batteries have failed the periodic efficiency test. The batteries should be replaced by qualified personnel because they are no longer able to maintain the charge for a sufficient time.
How to fix Riello MSM 10 UPS not switching to standby mode?
If your Riello UPS is connected to the mains but doesn't switch to standby mode, it could be due to several reasons. First, check the connection to the input terminal, ensuring it follows the installation instructions. A missing neutral connection can also cause this issue; the UPS cannot operate without it, and its absence could cause damage. Also, check the 1/0 switch behind the door and set it to 1 (if present) and make sure that the SWIN switch located behind the door is closed. Finally, verify that mains power is available and that no upstream protection device has been triggered. If a protection device has intervened, restore it after checking for overloads or short circuits.
What does S07 mean on my Riello MSM 10 UPS display?
If your Riello UPS display shows the code S07, it means the batteries are discharged. The UPS is waiting until the battery voltage rises above the established threshold value. You can either wait for the batteries to recharge or manually force start up from the “START UP” menu.
Why is my Riello MSM 10 UPS running on batteries even with mains power?
If the Riello UPS is operating off the batteries even when mains power is available, it could be due to the upstream protection device intervention. In this case, restore the protection, ensuring there is no overload or short circuit on the UPS output. Another reason could be that the input voltage is outside the accepted operating values. If this is the case, wait until the input voltage falls within the tolerance values, and the UPS will automatically switch over to mains power.
