3.3 USER INPUT WIRING
CAUTION
: DC common (Terminal 4) is NOT isolated from Input common (Terminal 7) or User common (Terminal 9). In
order to preserve the safety of the meter application, DC common must be suitably isolated from hazardous live earth
referenced voltage; or Input common and User common must be at protective earth ground potential. If not, hazardous
voltage may be present at the Signal or User Inputs, and Input or User common terminals. Appropriate considerations
must then be given to the potential of the Input or User common with respect to earth ground.
Terminal 8: User Input
Terminal 9: User Common

Shaded areas not recommended for counting applications.
The meter provides a choice of eight different count modes using two signal inputs,
A and B. The Count Mode selected determines the action of Inputs A and B. Section 5.1,
Input Setup Parameters, provides details on count mode selection and input action.
