Installing the Connector Block
Do the following for each connector block being
installed:
1. Use the MBC/RBC layout sheet to determine
the correct block position number.
The block position number is printed on the
mounting rail label as 1A, 2A, etc. (Figure 4).
2. Remove the protective tape along the
perforations to uncover the slot where the
connector block attaches to the Module BUS
(M-BUS).
3. Align the connector block mounting hooks with
the left edge of the mounting rail.
4. Rotate the free end of the connector block into
the M-BUS rail.
5. Verify that the mounting guides on the
connector block are aligned with the mating
M-BUS rail slot (Figure 4 and Figure 5).
6. Firmly press the connector block into the
M-BUS rail.
You will hear a light “click” when the connector
block is properly mounted”
CAUTION:
The connector block should easily
snap into place. If not, recheck the
alignment of the mounting guides with
the M-BUS rail.
Figure 4. Installing a Connector Block.
Repositioning or Removing a Connector Block
While pushing and holding the release tab
toward the mounting rail, rotate the block
out of the M-BUS rail (Figure 5).

Connecting the Pneumatic Lines
NOTE: If more than one AO-P module is being
used, you may daisy chain the supply lines.
Up to four connector blocks can be
supported by one 1/4-inch supply line.
1. Connect Supply air (S) to the open end of the
brass tee fitting.
Allow 5 psig (34.5 kPa) supply above the
maximum output value.
2. Insert a brass plug into the supply air extension
of the last connector block. See Figure 6.
3. Connect the Return line from the controlled
device to the Return port (R) of the AO-P
connector block.
NOTE: To eliminate oscillation in the line, a
minimum of 30 inches of 1/4-inch
tubing is required between the AO-P
return (R) port and the controlled
device.
