Default Accelerometer to audiointerface

Hi,
I am working on a project, doing some data acquisition with several accelerometers(ADXL326 datasheet)
Using aMotu pre 8

I have designed this schematic for feeding the accelerometers with 3V supply from the 48V Phantom Power from the Motu. Problem is, the outputs of accelerometers to the XLR, have i made this connection the right way? Im measuring 7-8V at the Accelerometer outputs if i connect it to the, and no change in the output when i turn the accelerometer.
If i dont connect the acc-output, but measure with reference to ground, it works just fine(although with some noise spikes).

Any one can see some problems with this circuit?
