1: Clean all ground rod end(s) with abrasive to assure a good electrical connection. Keep all
ground straps untwisted, clear of standing water, with a drip loop, and as short as possible.
Secure the strap to the ground rods with the provided clamp and coat with grease.
Cover the connections to protect from water and condensation.
2: Connections to the Scale Module are installed by bolting to the weighbridge. Scrape /
sand enough paint / coating away to make a good electrical connection and secure with the
provided hardware.
3: Connect the strap to the Scale Module using the provided bronze set screw terminals and
coat with grease AFTER the connection has been made.
4: Ground rod #6 should be located near the interface conduit. It is used to connect to the
isolated ground of the Pit Power Supply (PPS) Acc 2001-1A only. Connect the internal white
ground wire from the PPS to that rod.
5: #6, #7, and #8 Ground Rods are intended to ground the approach rails. These should be
installed and correctly connected with ground braid to the Anti-creep assy's (not provided by
Fairbanks). Refer to illustrations 50614_5, 50614_6, and Appendix VII.
