Installing the Termination Board
To install the termination board:
1. Remove the controller from its packaging and separate the top and bottom frames.
2. Using the bottom frame (with the termination board) as a template, mark the location of the four mounting holes and
the grounding screw on the mounting surface.
3. Set aside the controller and then drill holes for #8 (4 mm) screws at the marked locations.
4. Drill a 1/8 inch diameter pilot hole for the supplied grounding screw.
5. Secure the controller to the mounting surface with the enclosed using #8 (4 mm) screws (not supplied) in the mounting
holes.

Installing the Main Circuit Board
The controller does not ship with the top plastic frame installed. The board can be kept in the office and programmed while
the enclosure is mounted and wired. After programming has been completed, connect the circuit board to the termination
board.
To begin, verify that the 24 Vac power cable is not connected to the termination board and then install the main circuit
board as shown in Figure 3, p. 5:

1. Hold the top frame (A) at a 90° angle to the bottom frame (B).
2. Connect the 60-pin cable (C) to the 60-pin cable ejector slot (D) by pressing down firmly on the cable until the ejector
tabs collapse and snap over the ends of the cable. Then, connect the 20-pin cable (E) to the 20-pin slot (F).
3. Align the snaps on the top frame (G) with the mounting locks on the bottom frame and then push the two frames
together in the direction indicated by the arrows.
Note: You will hear a click when the frames connect. For controllers with an operator display, connect the operator-
display cable to the circuit board.
4. Install the supplied grounding screw (6-32 x 2 inch, thread-rolling screws) into the assembly and turn it into the
sheet metal backing.
