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.
