Installing Atlas 9800 Power Supply (M07588A00X)
To install the Atlas 9800 Power Supply (M07588A00X), proceed as follows:
Always remove AC power from the pump/dispenser before servicing the unit. Failure to
turn off the unit before servicing may result in serious injury or death.
WARNING
1 Check the existing power supply. For the correct replacement part number, refer to

“Atlas 9800 Power Supply (M07588A00X)” on page 5-28 .
2 Ensure that the AC power to the pump/dispenser has been disconnected.
3 Disconnect the AC power cable from the P3 connector. Disconnect the DC cables from the P2
and P1 connectors.
4 Unscrew and remove all screws that hold the power supply. Retain the screws for installing the
new power supply.
5 Remove the power supply. For models with plastic standoffs, after the screws have been
removed, carefully unsnap the power supply from the standoffs and remove it. Remove any
standoffs that may have remained on the power supply and place them back into the plate
where the power supply was mounted.
6 Install the new power supply on the standoffs. Ensure that the P1 connector is closest to the
CPU Board and P3 connector is away from the CPU. If the pump model is 9822 or 9823, the
P1 connector is closest to the pump handle assembly.
7 Reinstall the screws removed in step 4 . For models with plastic standoffs, carefully push the
power supply onto the plastic standoffs before installing the screws.
8 Reconnect the following:
• Cables and AC power to the P3 connector.
• Display Backlight to the P2 connector.
• CPU DC to the P1 connector.
