Connect and wire the MELSEC-GOT series equipment as instructed below.

If the MELSEC-GOT series equipment is configured in a way that differs from the fol owing

instructions then the system will not comply with EMC specifications.

@

Be sure to install a ferrite core when the Power Supply Module's power wires and

ground wires are within 100mm (3.94 inch) of the Power Supply Module's terminal

block. The ferrite core is packaged with the Power Supply Module. (ZCAT303E-1330

made by TDK.)

@

Be sure to connect the ground wire (LG wire) to the protection conductor.

@I Be sure to install a FG mesh wire between the Power Supply Module's FG terminal

and the FG mesh wire ground area of the EMC Box to prevent radiated noise frc:)m the

GOT and Communication Module. The FG mesh wire is packaged with the 130wer

Supply Module.

@

Be sure to install the FG mesh wires of the Bus Connection Module and Serial Com-

munication Module to the FG mesh wire ground area of the EMC Box to prevent

radiated noise from the GOT and Power Supply Module.

@

Be sure to peel the shield covering from the white areas (2 areas) of the cable covering

of the connection cable (A8GT-AC30R4-EU, A8GT-A1 SC30NB-EU) to the GC:IT and

PC CPU control panels using cable clamps to prevent radiated noise from tht, = con-

nection cable.

@ To obtain an electric contact in the control panel installed in the EMC Box be sure to

remove the paint from the control panel surface where the installation will be made.
