Connecting Load Cell Cable
Shield Cable Connection
As a general rule, only connect the load cell cable's shield wire to the module's shield
terminal. This is because when there are multiple ground points, it becomes easier for noise
to occur as a result of a ground loop. However, when there are higher priorities than noise
prevention, such as explosion prevention systems or static electricity release routes, this rule
does not necessarily need to be followed.
Load Cell Terminal Connections
Two types of load cell connection are available: 6-wire connection and 4-wire connection.
For high precision and stable weighing, 6-wire connection is recommended.
