New Installation Instructions
1.
Using the mounting rail as a template (Figure
1), mark the screw holes where you will install
the controller assembly.
2. Do one of the following:
•
If using the self-tapping screws provided:
Using the drill and the hex nut bit, fasten the
mounting rail.
•
If not using the self-tapping screws: Drill
two 1/8-inch (3 mm) pilot holes, then fasten
the mounting rail with No. 6 or No. 8 screws.
3. Place the ESD wrist strap on your wrist and
attach it to a good earth ground.
4. Carefully remove the controller assembly from
the anti-static bag. Center it over the mounting
rail and snap it securely into place.
5. Connect the Floor Level Network (FLN). See
Figure 4.
6. Connect the point wiring as shown in Figure 7.
NOTE: Wiring to DI3/AI3 requires a clamp-on
ferrite filter (Figure 6). Strain relief must be
provided to ensure long-term effectiveness
due to added weight of the filter.

CAUTION:
The Controller's Digital Outputs (DOs)
control 24 Vac loads only. The maximum
rating is 12 VA for each DO. Use an
interposing 220V 4-relay module for any of
the following:
•
VA requirements higher than
maximum.
•
110 or 220 Vac.
•
DC power.
•
Separate transformers used to
power the load.
and a Common (C) terminal. Terminate
both connections of a 24 Vac load directly
to the controller board. Actuators use two
DOs and require three connections.
