Foundation Construction
1. Prepare a hole for the foundation and wiring 
conduit using the minimum recommended 
dimensions shown in Figure 3.
*Note: Refer to local electrical codes for 
required depth of buried wiring .
2. Trench to the foundation site as required for 
each wiring run.
3. Position straight and sweep elbow conduit 
sections in foundation hole as shown. Tape 
the conduit ends to seal out dirt. Backfill 
soil to form a 6” (15.2cm) foundation depth. 
Conduit should not extend more than 
2” above the finished top surface of the 
foundation.
4. Prepare the sides of the foundation hole 
with wood forms.
5. Prepare the mounting bolt positioner with 
the 5/16 x 4-1/2” bolts and nuts (provided) 
as shown in Figure 3. The threads should 
extend 2” (51mm) from the top surface of 
the bolt positioner.
6. Pour concrete into the formed foundation 
hole. Press the mounting bolt positioner into 
the concrete until it is flush and level with 
the foundation surface and aligned with the 
conduit.
7. Finish the concrete with a level flat area for 
the pedestal base (13” x 13” [33cm x 33cm] 
for the metal cabinet or 16” x 16” [41cm x 
41cm] for the plastic cabinet). To prevent 
pooling at the base of the pedestal, add 
a slight taper away from the cabinet base 
contact area. Allow concrete to sufficiently 
harden before continuing.
8. Remove the hex nuts from the mounting 
studs. Carefully position the controller onto 
the studs. Install a flat washer and a hex nut 
on each stud and tighten securely.
