MM6 Cyberpower UPS - Troubleshooting


This article is a guide for troubleshooting issues with the Cyberpower UPS on an MM6 kiosk. This component provides uninterrupted power during short outages and surge protection for the kiosk components. All other components in the kiosk receive power from the Cyberpower UPS, so the unit must be turned on when the kiosk is in use.



  • MM6 (all variations)
  • MM6 Plus MicroMarkets (all variations) 


Normal Operations

The kiosk has a window on the back to view the status of the Cyberpower unit. Check the window on the back of the kiosk at the bottom. Under normal conditions, the Power LED should be lit up green, and the display should show the line voltage at approximately 120 Volts. 

  1. To power up the Cyberpower UPS, hold down the Power button and listen for one long beep followed by a short beep. Release the power button immediately. The display should match the below image.
  2. When powering down the kiosk, first open the kiosk door and power down the PC by pressing its power button.
  3. Once the PC has powered down, you can turn off the Cyberpower unit by holding down the power button and listening for one long beep, then two short beeps. Release the power button after the short beeps and the Cyberpower UPS will power down.

Common Issues

The most common issue is a lack of power to the Cyberpower unit or a fault on the unit itself. Make sure the Cyberpower is plugged into an outlet that has adequate power to supply to the kiosk.

Removing the Cyberpower from MM6

Tools Required 

  •  1/8” hex wrench
  • 5/32” hex wrench



  1. Unplug the kiosk

  2. Using a 1/8” hex wrench, remove the 4 screws on the lower cover plate and remove the plate. If the kiosk is mounted to a countertop, you may need to loosen the mounting hardware to give the plate room to be removed.
  3. Unplug all components from the UPS
  4. Remove the 3 hex screws on the hold-down by using an 1/8” hex wrench
  5. Remove both side trim covers by removing the upper and lower mounting screws. Make sure to retain the spacers under the covers for re-installation.

    • If there is an XP unit installed on the kiosk, it must be removed before continuing. Unplug the XP from the kiosk. Remove the hex screw from the back of the XP unit's mounting leg with a 1/8” hex wrench, and 3 mounting nuts with a 7/16” wrench. Once the unit is removed, be careful to lay the XP on its side to prevent damaging the cables on the back of the printer unit.
  6. Unhook the door latch spring and set it aside
  7. Remove the larger hex screw securing the UPS hold-down on each side of the kiosk by using a 5/32” hex wrench. The screw is approximately 4” from the bottom of the kiosk, centered on the side rail (see photos).
  8. Remove the UPS hold-down from the kiosk
  9. Lift the UPS slightly to de-seat the feet on the UPS from the kiosk bottom plate. Slide the UPS toward you slowly, taking care to prevent it from catching on the plastic back cover of the kiosk. Push up slightly on the area around the UPS viewing screen to keep the UPS free of this cover as shown. As you pull the UPS, make sure the power cord does not catch on the plastic cover and clears the hole in the cover.


Installing the Cyberpower in the MM6

  1. Feed the power cable through the triangular hole in the back of the plastic lower cover. Make sure to feed the plug from the inside of the kiosk to the outside for correct installation.
  2. Slide the Cyberpower unit into the kiosk. Its feed will lock into the corresponding holes in the base of the shell when installed correctly. Make sure to keep the power supplies and cables to the side of the UPS: do not let them get pushed to the back of the shell, as they will aid in later installation.
  3. Install the hold-down bracket over the UPS. Secure with the side screws at the top using a 5/32” hex wrench.
  4. Install the 3 hold-down screws in the bottom of the hold-down bracket ny using a 1/8” hex wrench.
  5. Re-hook the spring from the hold-down bracket to the latch assembly.
  6. The side trim pieces need to be installed next. Locate the trim piece with the notch in it, as shown below. This goes on the latch/hinge side of the kiosk. Insert the long hex screws through the trim piece and add a nylon spacer to each. When installing on the hinge side, tuck the trim piece under the hinge for proper connection. Tighten hex screws with a 1/8” hex wrench.
  7. Plug power supplies back into UPS. Utilize the plug locations on the right-hand side of the UPS to re-connect, as these are both surge-protected and have the battery backup.
  8. Install the lower front cover plate using 4 hex screws and a 1/8” hex wrench. You may need to lift the front of the kiosk slightly to slide the lip of the cover plate under the front edge of the kiosk.
  9. Plug the kiosk back in and check that all components are functioning. If the screen, PC, credit card reader, or router do not have power, double-check the connection of the power supplies to the UPS. Make sure the status lights on the UPS are visible and lit up, as shown in the first step of Normal Operations.
