b) Be sure to ground the protective ground terminal of the GOT main unit to the
control panel.
At this time, keep the length of the ground wire grounding the control panel to
within 120mm (4.72inch).
Moreover, be sure to install the ferrite core (TDK brand ZCAT3035-1330)
within 70mm from the protective ground terminal.
(The ferrite core is not used when using the A985GOT RS-422 connection.)

c) When connecting CC-Link, use the grounding wire of the FG1 terminal on the
CC-Link communication module to connect to the FG terminal of the GOT
power section.
Use a grounding wire of 300 mm or less.
Also, attach the ferrite core (ZCAT3035-1330) within 70 mm of the FG terminal
of A8GT-J61BT13.
