 RFI Suppression 

The following instructions describe the load cell connection using the existing plastic gland 
connectors.  Note that using the plastic gland connectors does not provide RFI Suppression. 
 

1. 

Referring to Figure No. 1, choose a gland connector for the load cell cable and loosen it. 

2. 

Slip the single cable from the load cell or load cell junction box through the gland connector 
and into the enclosure.  

3. 

Referring to Figure No. 7, remove 3 inches (not 5 to 6 inches) of the outer insulation jacket 

4. 

Next, remove 1/4 inch of insulation from each of the four wires and shield (without sense 
leads) or six wires and shield (with sense leads). 

5. 

Referring to the table below (or on the circuit board) for terminal connections, connect each 
of the wires to terminal block P2 or P3.  Refer to Figure No. 12 for terminal block location.

6. 

To terminate a wire, use a small flat blade screwdriver and press down on the release bar 
for the terminal.  Insert the wire into the terminal opening.  Remove the screwdriver, 
allowing the release bar to return to its original position, locking the wire in place.  See 
Figure No. 9.

 

7. 

Repeat the procedure until all wires are in place. 

 
 

Load Cell Connections with Over 30 Feet of Cable 

On installations with over 30 feet of cable between the 225-DS and the load cells, sense wires 
should be used.  The sense wires must be connected between the +SENS, -SENS terminals 
on the 225-DS (Dual Scale Input Card) and the +EXCITATION, -EXCITATION wires of the 
load cells or the +SENS, -SENS terminals of the load cell trim board (or the section seal trim 
board).  Refer to Figure No. 12 for the location of these jumpers.
