(2) Grounding the LF602F type
Ground the external grounding terminal of the detector and the FG terminal of the converter (or ex­
ternal grounding terminal of the converter) securely (grounding resistance 100 Q or lower). Use
grounding wire material of IV wire 5.5mm^ or more. Do not share a grounding wire with other
instruments where grounding current may flow. (An independent grounding is preferable.)
If it is difficult to perform grounding work at the detector side because of a pit installation or other
reasons, use a 3-core cable for the excitation cable and connect the E terminal of the detector to the E
terminal of the converter. (The E terminal of the converter is internally connected with the FG termi­
nal and the converter case.)

Wiring between Detector and Converter (For
grounding the detector, see Figure 5.5 below.)

Wiring between Detector and Converter
(when grounidng of the detector is difficut)
If the piping material is conductive, connect the
grounding wires to the both ends of the piping flange.
If the piping material is non-conductive, perform grounding
resistance 100Q or less.
