5. Secure the top of the USM2.5 card to the Inverter Module with the PEM fastener. The lower portion is
covered by an optional blanking plate. Use 2 #6 screws to secure the blanking plate.

7. Reinstall the Inverter Module:
• Align the metal shield in the upper and lower card-guides.
• Using ONLY the Inverter Module’s handle (do not apply pressure to the front panel) firmly drive
the module back into the connectors. The connectors are designed to be made with reasonable
force.
• The thumbscrews are not intended to aid in making these connections, but to secure the Inverter
Module to the chassis.
• Reattach the ribbon cable to the inverter module.
8. If the Inverter Module is correctly seated, the front panel Smart Display will start-up, and the “Inverter
Disconnected Alarm” will NOT be active.
