6 RoughDeck Low Profile Floor Scale
2.4.2 Mounting Plate Installation
For permanent applications, the scale should be secured to the floor to prevent sideways movement. Two mounting
plates, with holes that slightly exceed the foot diameter, are available as an option for that purpose.
Lift the scale so that the feet are approximately one inch off the floor. Slide mounting plates under two diagonally
opposed feet. Lower the scale back to the floor, and position the plates as shown in Figure 2-2 so that the boltdown
holes are accessible from above.
Using the mounting plates as templates, drill pilot holes into the floor for suitable anchor bolts. Bolt the plates to
the floor using

-in anchor bolts (

-in bolts for 20K and 30K-lb capacity scales). Recheck foot adjustment and
deck level after this operation.
For installations using access ramps, mounting plates are not necessary as the ramps have built-in mounting plates
to secure the scale feet

2.5 Electrical Interface to the Indicator
Twenty feet of 6-wire cable to connect the scale to the weight indicator is supplied with each scale.
NEMA 4X
If your scale uses the NEMA 4X junction box, push one end of this cable into the junction box through the strain
relief bushing hole in the tray. Connect the wires to the INDICATOR terminal (shaded area of Figure 2-3) as shown
in the load cell specifications. Pull out excess and tighten the strain relief bushing to hold the cable snugly.
Standard Junction Box
If using the standard junction box, put the cable through the hole in the junction box tray. Slide the two parts of the
strain relief flex fitting onto the cable with the threaded piece inside the faceplate and the flexible spiral portion to
the outside. Push the cable end into the junction box and connect the wires to the INDICATOR terminal. Pull out
excess cable and tighten the two parts of the strain relief flex fitting to hold the cable snugly.
