Using the two handholds provided on the Power Module, lift up at least 1 inch and then outwards to remove the
Power Module.
10. Insert the replacement Power Module by reversing steps 1 through 9. Tighten the nuts in step 8 to a torque value
of 60 to 68 in-lbs. Refer to Table 1 for model specific locations of the transformer wires, fan wires and ribbon cables.

Replacement of the Front Cover
section.
Replacement of the Front Cover
Tools
Phillips screwdriver
Procedure
To replace the front cover:
1.
Prior to replacement of the cover ensure no tools or loose hardware has been left inside the chassis. Also ensure
that all electrical connections have been made. These include the AC input and output terminations, ground
termination, Remote cable, Auxiliary wires, Battery Temp cable, two ribbon cables (both ends), two fan cables, and
the four or six connections from the Power Module to the PCBA Module.
NOTE
: For Radian models that have only one Power Module there is only one ribbon cable, one fan, and either two
or three connections from the Power Module to the PCBA Module. In this case it is necessary to use the “Left”
connections
2.
Use a Phillips screwdriver to insert the 22 screws that attach the cover to the chassis. Tighten screws to “finger
tight,” as excessive torque may warp the cover. Refer to Figure 2.
Power Up
After replacement of internal items it is necessary to power up the Radian inverter and other related
electronics to check that the repair has been successful. If only a Power Module has been replaced, please
proceed through the steps below, ignoring those pertaining to firmware updates and configuration files. If
the PCBA Module was replaced, it may need to be programmed in order for proper system operation.
Additionally, the firmware revision number will need to be the same as the firmware of other Radian
inverters in the system if they are present.
IMPORTANT: MATE3 Upgrade
When replacing the PCBA Module, make certain to upgrade the MATE3 firmware to the
latest revision. If it is not upgraded, the MATE3 may not recognize any new inverter
functions. This will make them inaccessible to the user. See the OutBack website,
or AOE website www.alpha-outback-energy.com
, for the
latest firmware revisions.
