4.5Grounding 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 8) 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. Connect the grounding wire to the grounding system. Leave sufficient slack in the grounding wire to allow it to be routed into the cabinet after the cabinet is mounted on the pad.
4.6Mounting the Cabinet on the Concrete Pad
The following sections provide instructions for mounting the
Warning: Use appropriate lifting equipment when moving or installing the cabinet. Do not stand under the cabinet as it is being hoisted into position for installation. A failure of the lifting equipment could result in serious personal injury.
4.6.1Mounting the ACE-142S Cabinet on a Concrete Pad
Use the following procedures to mount the
1.Remove the plastic plugs that are installed in the threaded corner holes of the PMF and clean off any concrete that may have adhered to the top of the PMF.
Note: Make sure all remnants of concrete are removed from the PMF prior to mounting the cabinet. It is not necessary to use shims to level or align the cabinet as long as the top surface of the PMF is clean and free of any installation debris.
2.If a ground spacer will not be installed, proceed to step 7. If a ground spacer (accessory) will be installed, align the ends of the left ground spacer section with the ends of the right ground spacer section and then press the two sections together.
3.Place the assembled ground spacer in position for mounting on the PMF as shown in Figure 10.
4.Align the mounting holes in the ground spacer with the mounting holes in the PMF.
5.Secure the ground spacer to the PMF using the four capscrews, four lock washers, and four flat washers provided with the cabinet. Tighten all capscrews securely.
6.Open the rear door of the cabinet and remove the back section of the cabinet bottom cover as described in Section 5.1. Then return to step 7 of this procedure to finish mounting the cabinet.
