4.3 INPUT WIRING
CAUTION: Power common (PWR COMMON) is NOT isolated from input common (INP COMM). In order to preserve the safety of the meter
application, the 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 Signal or User Inputs and input common terminals. Appropriate considerations must
then be given to the potential of the input common with respect to earth ground; and the common of the plug-in cards with respect to input common.
