WARNING: DO NOT CUT THE LOAD CELL CABLE! 

 

3.   Pull the load cell cable out of the conduits built into the frame channels. The chase 

wire will be used to pull the new load cell cable through the formed channel. 

 
4

.  

Install the new load cell by reversing the preceding steps.  

 
5.   To  verify  correct  load  cell/junction  box  terminal  matching,  see  the  numbers  on  the  terminals 

inside  the  junction  box  and  the  corner  numbering  diagram  in 

Figure  1:  Load  Cell

 

Configuration

 and 

Figure 2 Junction Box Connections.

 

 
6.   Position load cells with load cell alignment arrow pointing up toward the deck. With the torque 

wrench, tighten all mounting bolts to 75 ft./lbs. 

 
7.   Route the load cell cables in each corner so that the cable is free from possible contact with the 

load cell or load foot. Pull cable towards junction box, (not to tight) and coil up extra length with 
cable ties and securely store inside channel per figure 3 

(Below).

 

 
8.  Pass end of load cell cable through cable fittings in the NEMA 4X junction box.  
 

Re-calibrate scale after a load cell replacement. Follow the calibration instructions in  Chapter  8
