Installing the DIN Rail Mount Controller
Figure 3a
Sub-Panel Mounting
1. Using the controller as a location template, mark both mounting holes.
2. Drill and tap two 2.7 mm (0.106 in) diameter holes in the desired panel location. See Figure 3a above for hole
locations.
3. Mount the controller using two M3.5 (#6) screws.
DIN Rail Mounting
1. Place the DIN rail upper mounting clip on the top edge of the DIN rail. See Figure 3a. DIN rail spec, DIN
50022, 35 mm x 7.5 mm (1.38 in x 0.30 in).
2. Press down firmly on the top back edge of the DIN rail bracket and push in on the bottom, front edge of the
bracket. The controller “snaps” securely onto the rail. See Figure 3a. If the controller does not snap on, check to
see if the DIN rail is bent. Minimum clipping distance is 34.8 mm (1.37 in), the maximum is 35.3 mm (1.39 in).
Removing the DIN Rail Controller
1. Remove power from the system.
2. Remove all the wiring connections from the back of the controller.
3. While pressing down on the top, back edge of the DIN rail bracket,
pull forward on the bottom, front edge of the DIN rail bracket. See
Figure 3a.
Removing the Controller from the DIN Rail Bracket
1. Remove power from the system.
2. Remove all the wiring connections from the back of the controller.
3. Remove the DIN rail bracket from the DIN rail.
4. Insert a flat blade screwdriver between the DIN rail bracket and
the case. Rotate the screwdriver to release the DIN rail bracket
hooks from the ridges on the case, while firmly pushing the con-
troller out the front of the DIN rail bracket. Alternate back and
forth between the top and then the bottom. Be sure to support the
controller as it comes out of the bracket. See Figure 3b.
