Step 4: Properly Coiling the Cables
The excess SJB and Load Cell Cables must be non-inductively coiled as shown,
below. Note that when coiled in this manner, there will be an equal number of right
hand and left hand coils. See Figure 30.
DO NOT CUT THE CABLES.
Use wire ties to secure the excess cable coils to the bin structure, as shown.
Step 5: Grounding the System
Ground Rod Specifications:
The ground rod must be 8' or 2.4 meters long (minimum) and must be free of non-
conductive coatings, such as paint or enamel. The ground rod must be made from
either: 1) 3/4" (19 mm) diameter or larger galvanized pipe, or 2) 1/2" (13 mm)
diameter or larger copper-clad or solid copper rod.
