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.
