1.0 Introduction
The Summit 3000 floor scale provides exceptional performance and is an economical solution in light industrial applications.
The scale is a fully electronic, low profile floor scale that comes in sizes from 36'' x 36'' (914 mm x 914 mm) to 60'' x 60''
(1524 mm x 1524 mm), and capacities from 2000 to 10,000 lb (1000 to 5000 kg). All models use four corner-mounted, NTEP-
certified, alloy steel shear beam load cells, with the cells recessed into the frame channels for protection. All models are
shipped pre-trimmed, so corner corrections are not needed on arrival. However, the signal trim summing board is enclosed in a
durable ABS enclosure that has a convenient top-access for future corner corrections.
Other available options include custom frames for pit installations and access ramps for all sizes.

2.0 Installation
The following sections describe the correct installation procedures for the Summit 3000 floor scale.
2.1 Scale Location
The scale must never be loaded beyond its capacity, even momentarily.
• Select a site where overweight loads can maneuver easily without crossing the platform.
• Avoid areas where damage could occur from side impacts of wheels or forklift tines.
• Avoid areas where falling objects could cause shock damage.
• Avoid areas where water may damage a scale not meant for a wash-down environment.
• The scale must be level within 1/4'' (6.35 mm). Choose a site where the floor is level to this standard to avoid excessive
shimming. The floor may require modification if unable to select and area up to standard.
• For systems where the scale is connected to a 120V AC circuit, the instrument must be directly connected to an earth
ground with a ground interface cable of no more than 3  resistance throughout its length.
2.2 Unpack Scale
Remove all packing material and inspect scale for visible damage caused during shipment. Report any damage to the shipping
company and Rice Lake Weighing Systems immediately.
Figure 2-1. Proper Lifting Technique
Lift the scale only with a properly designed spreader bar. Lifting force must be vertical to avoid bending the eye
bolt.
Eye bolts must be inserted in the top of the scale. Lifting should always occur with the top plate facing up and
the eye bolts securely attached through the nuts welded to the bottom of the top plate. Lifting from the bottom of
the plate could cause nuts to break loose and the scale to fall.
IMPORTANT
(5' x 5' or smaller and/or 10,000 lb or less capacity).
Use one 1/2-20NF eye bolt inserted into the center of
top plate for lifting.

2.3 Adjust feet
The scale feet are secured with a jam nut (located next to each load cell) during shipping to protect the load cells.
1. Loosen the jam nut.
2. Screw one foot into each load cell and turn until each foot touches either the load cell or the underside of the deck.
3. Unscrew each foot three complete turns.
4. Place a spirit level on the deck.
5. Adjust any high corners until they just contact the floor surface.
6. Recheck the deck with the spirit level, when all feet contact the floor, to ensure it is within 1/4'' of level.
Figure 2-2. Jam Nut Location on Scale Foot
2.4 Anchor Plate Installation
Optional floor anchor plates (PN 75819) are available for permanent applications and should be secured to the floor to prevent
sideways movement of the scale.
1. Using proper lifting technique (Figure 2-1 on page 3), lift the scale so the feet are approximately one inch off the floor.
2. Slide mounting plates under two feet, diagonal from each other.
3. Lower the scale back to the floor and position the plates so that the boltdown holes are accessible.
4. Using the mounting plates as templates to drill pilot holes into the floor for suitable anchor bolts.
5. Bolt the plates to the floor using 1/2'' anchor bolts.
6. Recheck foot adjustment and deck level.
For installations using access ramps, mounting plates are not necessary, the ramps have built-in mounting plates.

2.5 Electrical Connections
2.5.1 Electrical Grounding
For systems where the scale is connected to a 115 or 230 VAC circuit, the indicator must be directly connected
to an earth ground with a ground interface cable of no more than 3  resistance throughout its length.
2.5.2 Electrical Interface to Indicator
To connect the scale to the weight indicator, 20' of 6-wire cable is supplied with each scale. The junction box is accessible
through an access plate located on the top of the scale.
Use the following steps to wire the junction box.
1. Remove the access plate.
2. Remove the four screws using an Allen wrench.
3. Lift the junction box assembly out of the scale deck.
4. Remove the top of junction box.
Figure 2-4. Junction Box Opened
5. Push the cable end into the junction box through a cord grip.
6. Connect the wires to the indicator terminal (Figure 2-4) as shown in Table 2-1.
7. Pull out excess and tighten the cord grip to hold the cable snugly.

8. Route the cable so that it is protected from damage. Leave a loose coil of excess cable under the scale to allow for
servicing and cleaning.
9. Connect the cable to the indicator. See the indicator installation manual for wiring information.
10. If necessary, trim corners as described in Section 2.2 on page 3.
11. Check all strain relief fittings for tightness.
12. Put the cover back onto the junction box assembly and place the junction box back into the floor scale cutout.
13. Secure the Summit 3000 floor plate.
