This appears to be an electrically-controlled outlet box. The front indicates is is an AXS Micro Access Power Unit. It has a circuit breaker and an "Outlets On" indicator. As usual, I don't have a manual or any other documentation for this device. Can anyone identify the pinout of the control cable?

The back has a hard-wired AC power cord and a DIN plug for some kind of control cable. The label shows this device to be from Dynaflow Systems, Inc. (Click on either image for a larger version.)

The lines from the DIN connector appear to be wired to a control relay. (Click on the image for a larger version.)
