4.Verify that the PMF and form are level. Depending on the landscaping requirements, the top surface of the concrete pad may be 0 to 3 inches (0 to 7.6 cm) above the final grade. The weld nuts are covered with plugs which must be left in place until the enclosure is mounted.

5. Pour the concrete to form the pad but do not pour concrete into the center area of the PMF.
Note: Allow some concrete to flow under the flanges on the bottom of the PMF so the PMF will be locked in place when the concrete hardens. However, do not allow concrete to fill the center of the PMF. If necessary, partially fill the center of the PMF with sand or gravel to prevent an inflow of concrete.
6.Remove the top framing and the temporary support wires when the concrete is ready to be finished.
7.Allow concrete to cure before proceeding with the installation.
5 GROUNDING SYSTEM INSTALLATION
Install a grounding system (not provided) that meets all local electrical codes. Check local codes for grounding system installation, use of clamps, wire size, and any other grounding requirements. Typically, #6 AWG copper wire is used for the ground wire.
If the grounding system includes a ground rod, install the rod (see Figure 2) within the PMF opening at the indicated point. When installed, the top of the rod should be located 1 to 2 inches (2.54 to 5.08 cm) below the top of the finished concrete pad.
