Grounding - Toshiba LF516 Instruction Manual

4.4 Grounding

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.
DON'T
Ground as shown in Figure 4.10. Make the grounding wire as short as possible. Use
grounding wire material of IV wire 5.5mm
with other 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
piping flange.
