4 CW90B/90XB Bench Scale Installation Manual
2.3 Connecting the Load Cell Cable
The CW-90B and CW-90XB come with a standard 10 foot or 34 inch color-coded load cell cable.
See your indicator manual to determine the prope
r load cell cable input connectors.
Important
Do not cut the load cell cable. The load cell cable is tem
perature compensated for an exact cable length.
2.4 Grounding the Scale Base
Scale bases can build up static electricity during weighing operations. If powerful enough, this charge can travel
through the load cell cable to the indicator. To prevent this, all bench scales attached to indicators by just a load cell
cable should be adequately grounded to discharge static and transient electrical surges.
A chassis ground screw is located on the
bottom of the platform. Item 7 in Figure 6-1 is an 8-32 NCx3/16 screw
used to facilitate grounding. Use a ground wire of at least 18 gauge copper
to connect this screw to the same earth
ground as the attached indicator.
