Before connecting signal wires, the Input Range Jumper must be verified for proper position.

CAUTION: Sensor Input B common is NOT isolated from user input common. In order to preserve the safety of the meter application, the sensor input

common must be suitably isolated from hazardous live earth referenced voltages; or input common must be at protective earth ground potential. If not,

hazardous live 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 common; and the common of the isolated option cards with respect to input common.
