8 UMC 600IS Installation Manual
2.6 Load Cell Wiring
All units are equipped with a six-wire load cell
connector. Condec supplies load cell cable in various
lengths (see Table 2-3 on page 5). One end of the
cable attaches to the indicator; the other end has
stripped and tinned wires for connection to a junction
box. The UMC 600IS is supplied with a blank six-pin
connector that can be attached to existing load cell
cables by the installer.
Figure 2-5 shows the load cell output connector and
the location of J1 on the back of the indicator.
