(2) Connection of terminal resistor to the GOT
When connecting a terminal resistor to the GOT, always connect it in the following
position.
The terminal resistor is contained in the package of the Master module.

POINT
• The "terminal resistors" supplied with the Master module must be connected to
the modules at both ends of data link. (Connect them across DA-DB.)
• Connect the shield wire of the CC-Link dedicated cable to "SLD" of each module.
Since "SLD" is connected to "FG/FG1" internally, always ground the FG terminal
and FG1 terminal to the protective ground conductor.
• The FG terminal of the GOT power supply and the FG1 terminal of the A8GT-
J61BT15 must be connected separately.
