Do not tighten the load cell cable mounting clips yet.

2. Push in and hold the quick-connect lever of the wire connectors with a small screwdriver.
3. Insert the wires into the appropriate wire openings for each load cell (

Table 2-1

4. Release the screwdriver to allow the spring-loaded gate to close and lock the wire in place.

Do not cut load cell cables.
