4.3.3 Grounding Cautions
(a) Dedicated Ground - best *1
PL
Other
device
• Set up a dedicated ground when using
the rear panel’s FG terminal.
(b) Shared Ground - allowed *1
PL
Other
device
• If a dedicated ground is not possible,
use a shared ground, as shown in figure (b).
• The grounding point must be as close
to the PL as possible, and the grounding wires must be as short as possible. If the wires must be long, use
thick, insulated wires and run them
through conduits.
(c) Shared ground - not allowed

4.3.4 Cautions When Connecting I/O Signal Lines
• I/O signal lines must be wired separately from charged lines. If the power cord
needs to be wired together with the (I/O) signal lines for any reason, use
shielded lines and ground one end of the shield to the PL’s FG terminal.
• To improve noise immunity, attaching a ferrite core to the power cord is recommended.
*1 Use a grounding resistance of less than 100 Ω and a 2mm2 or thicker wire, or your
country’s applicable standard. For details, contact your local PL distributor.
