Do not wire cables and replace parts
when power is supplied.
Wiring work and replacing
parts in the power-on state
may cause electric shock.
(1) Grounding of the LF414/LF600F, LF414/LF610F type
Ground as shown in Figure 4.10. Make the grounding wire as short as possible. Use grounding
wire material of IV wire 5.5mm
instruments where grounding current may flow. (An independent grounding is preferable.)
Conductive material pipe
Example: Metal, etc.
• If the piping material is conductive, connect
the grounding wires to the both ends of the

• If the piping material is non-conductive, perform
grounding (grounding resistance 100Ω or less).
