2-6B Removal of the Front Cover
The inverters are designed to work without the front cover in your MaxFlight simulator, and they should
already be removed and shipped in a separate package. Remove the front cover from new inverter as follow
when replacement is needed.
1) Hold both sides of the front cover top and gently push the front cover down.
2) Hold down the front cover and pull it toward you to remove. (The front cover
maybe removed with the PU (FR-DU04) on.)
2-7 Inverter Replacement
The inverter can be changed with the control circuit wiring kept connected.
1. Remove the mounting screws in both ends of the control circuit terminal block.
2. With both hands, pull down the terminal block from the back of the control circuit terminals.
3. When installing the terminal block to a new inverter, exercise care not to bend the pins of the
control circuit terminal block connector.
4. Disconnect all main circuit terminal wirings.
5. Unscrew the 4 mounting screws at the corners and remove the inverter unit.
6. Mount the new inverter.
7. Rewire the main circuit. See wiring diagram for jumper removal directions.
8. Reconnect the control circuit terminal block and tighten the screws.
After physical replacement of the inverter, it has to be configured to work for your simulator. The
operation panel (FR-DU04) is necessary to initialize this process, so make sure you familiarize
yourself with the panel with the attached information at the back of this manual. Also see
paragraph 3-8.
