Mounting to a flat surface
Use the provided mounting bracket to mount the ECM DIO8
to any flat surface.
1.
Run eBUS and I/O signal cables to the mounting site.
2.
If the ECM DIO8 is powering a sensor, run a cable to
carry 24 VDC from the sensor to the mounting site.
3.
If it is not already attached, secure the mounting
bracket to the back of the ECM DIO8, using the two
provided screws (see figure 8,
1
).

Attaching the Mounting Bracket to the ECM DIO8
4.
Place the ECM DIO8, with the mounting bracket
attached, against the mounting surface and mark the
position of the holes (see figure 9,
1
).
5.
Drill two pilot holes (diameter 11/16").
6.
Insert two screws into the mounting surface, using
fasteners that are appropriate for that surface. Leave
about 0.25" (6.4 mm) of the screw exposed.
7.
Fit the mounting bracket over the screw heads and
slide the device up or down so that the screw is seated
in the narrow slot of the bracket (
2
).
8.
Tighten the screws to secure the ECM DIO8 in place
(
3
).
9.
Connect the cables as described in

Mounting the ECM DIO8 to a Flat Surface
Plenum-space mounting
The ECM DIO8 is not plenum rated. It can be installed in a non-plenum area of the ceiling using the mounting bracket. If it is
installed in a plenum space it must be mounted in a closed junction box with plenum rated cable or conduit for all connections.
