4.3 INPUT WIRING
CAUTION
: Power input common is NOT isolated from user and input
commons. In order to preserve the safety of the meter application, the
power input 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 user and input commons with respect to earth
ground; and the common of the plug-in cards with respect to input common.
Before connecting signal wires, the Input Range Jumper should be verified for
proper position.
