Attaching Conduit

The Electrical Supply can be brought into the ATDDC4 enclosure from any of the top three vent-hole positions, from the back, or from either side. Conduit access is not available from the bottom.

Note: Optional plastic end-panels may be ordered (left VIS1551-L), (right VIS1551-R) that have access holes pre-drilled to allow side access.

If Conduit access is through either of the optional plastic end- panels, Conduit should NOT be used to support the weight of the Clock. The Clock must be properly secured to a wall.

Remove the vent cap from the selected mounting hole (if not accessing through side panels). Attach the conduit with locking nut and extend the wires into the enclosure.

Making the Connection

1.Slide the circuit board with display part-way back into the case. Connect the two black wires from the circuit board to the power- wires from the power cord or conduit using wire nuts. Connect the Ground Wires from the circuit board and from the power source (usually green) to the green ground screw on the inside of he enclosure.

2.Slide the circuit board fully into place, then slide the front lens into place. Note: the inside of the lens has a paper backing which should not be removed. The end with wider paper should go to the right. Replace the end caps and secure with the two Phillips head screws.

3.When the clock is energized, it will set itself, upon receiving the AirTime radio signal.
