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. Mini-

maximum is 35.3 mm (1.39 in).

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.
