3.4 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.
3.5 Electrical Interface to Indicator
Ten feet of 4-wire cable to connect the scale to the weight indicator is supplied with each scale. The junction box
is easily accessible through an access plate located on the side of the Summit SD-1150-WP. Use the following
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.

7. The cable must be routed to the indicator in a manner that will protect the cable from damage. This
method of cable protection in non-washdown applications are shown in Figure 3-3. When planning cable
routing, leave a loose coil of excess cable under the scale to facilitate future lifting of the scale for
