Do not use common grounding, since it can lead to an acci-
dent or machine breakdown.

3.2.4 I/O Signal Line Placement

Input and output signal lines must be separated from the power control cables
for operating circuits.
If this is not possible, use a shielded cable and connect the shield to the GP's
frame.
*1 Use a grounding resistance of less than 100W and a 2mm
or your country's applicable standard. For details, contact your local GP distributor.

• Check that the grounding resis-
tance is less than 100 Ω Ω Ω Ω Ω .
• The FG and SG terminals are
connected internally in the GP
unit.
• When connecting the SG line to
another device, be sure that the
design of the system/connec-
tion does not produce a short-
ing loop.
• The grounding wire should
have a cross sectional area
greater than 2mm
connection point as close to the
GP unit as possible, and make
the wire as short, as possible.
When using a long grounding
wire, replace the thin wire with
a thicker wire, and place it in a
duct.
If the equipment does not function prop-
erly when grounded, disconnect the
ground wire from the FG terminal.
