  • Page 6: Instrument Connection

    INSTRUMENT CONNECTION The instrument supply leads should not be in proximity of the incoming low-potential signals. Contactors, motors with larger input power should not be in proximity of the instrument. The leads into the instrument input (measured quantity) should be in sufficient distance from all power leads and appliances. Provided this cannot be secured it is necessary to use shielded leads with connection to ground (bracket E).
