Figure 3-5. Grounding Strap Location.
2. Attach lower end of grounding strap to either one of the two holes in the baseplate.

Upon completing the load cell mount installation, the lower module assembly bolts can be installed at each
location. Torque all module assembly bolts to 200 ft-lb.
3.4.3 Install Anchor Bolts and Grout
Install Anchor Bolts
Each mount requires two anchor bolts to prevent lateral motion. Two 7" x 3/4" anchor bolts with expansion heads
are supplied with the scale for each load cell. The anchor bolts are installed in holes in each module pier.
1. Use an industrial hammer drill with a 3/4" carbide masonry bit at least 36" long to drill anchor bolt holes.
This long bit allows the drill body to clear the side rail so the hole can be drilled nearly vertical. Hold the
bit as close to vertical as possible and drill a 3/4" hole at least 6" into the concrete pier beneath each anchor
bolt slot on both sides of the baseplate.
2. Place a washer and nut on each anchor bolt. Use a 24" long driver pipe with an inside diameter slightly
larger than the 3/4" bolt (shown in the illustration below) to drive anchors into the drilled holes until the
washer is solid against the baseplate.
Do not apply excessive force to the anchor bolt. Bending of the baseplate could occur.
