3.2 USER INPUT WIRING
CAUTION: Analog common is NOT isolated from user input common. In order to preserve the safety of the meter
application, the Analog and DC power common must be suitably isolated from hazardous live earth referenced voltage; or
input common must be at protective earth ground potential. If not, hazardous voltage may be present at the User Input and
Input Common terminals. Appropriate considerations must then be given to the potential of the input common with respect
to earth ground. Always connect the analog signal common to terminal 7.
