G3 Satellite
Installation Instructions
Introduction
The OSMAC G3 controller is designed for installation on a substantial concrete foundation with embedded conduit
of various diameters to enable power, field and earth ground wiring to be routed into the cabinet. A mounting bolt
positioner and basic mounting hardware components are included with each controller. Additional materials required to
complete the installation must be obtained separately. A material list can be compiled by reading through the instructions
completely prior to starting the installation.
CAUTION: For your protection and the safety of the product user, comply with all Caution and Warning Statements
within this document. All installation practices must comply with all applicable national and/or local electrical and
construction codes.

and wiring conduit using the
minimum recommended dimensions
shown in Figure 1.
*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 the straight and sweep
elbow conduit sections in the
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" (51mm)
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 1.
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 the
concrete to sufficiently harden before
continuing.
8. Remove the hex nuts from the
mounting bolts. Place the pedestal
on the pad ensuring all bolts pass
though the holes provided. Install a
flat washer and a hex nut on each bolt and tighten securely.
