Assembly
For load cell protection during shipping, the scale feet are shipped separately from the floor scale.
Screw one foot into each load cell and turn all the way in until the foot touches either the load cell or the
underside of the deck. Then unscrew each foot three complete turns.
Place a spirit level on the deck. Adjust any “high” corners not in contact with the floor by further unscrewing the
feet on those corners until they just contact the floor surface. When all feet are in contact with the floor, check the
deck with the spirit level to be sure the scale is within 1/4 inch of level.

Ten feet of 4-wire cable used to connect the scale to the weight indicator is supplied with each scale. The junction

steps to wire up the junction box.
1. Remove the two #10 x 3/8" screws.
2. Slide the junction box assembly out of the deck.
3. Open and remove the top of junction box.
4. Push the cable end into the junction box through a cord grip.
5. Connect the wires to the indicator terminal (Figure 3-2) as shown in Table 3-1.
6. Pull out excess and tighten the cord grip to hold the cable snugly.
