4.3 INPUT WIRING
CAUTION
: Power input common is NOT isolated from user input
common. 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 User Inputs and User Input
Common terminals. Appropriate considerations must then be given to the potential of
the user input common 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.
