About the cable used
Any device which utilizes a data communication function is susceptible to the wider effects of local EMC noise.
Therefore, when installing any communication cables care should always be taken with the routing and location of
those cables. The GOT identified on the previous page are compliant with the EMC requirement when the following
communication cables are used.
(1) Panel-mounted USB port extension
(2) Direct connection cable
(3) Ethernet connection cable
Shielded twisted pair cable (STP)
(4) PLC (manufactured by other company), microcomputer, temperature controller, inverter, servo amplifier,
CNC, MODBUS(R)/RTU or MODBUS(R)/TCP connection
Produce the cable (RS-232 cable, RS-422 / 485 cable) for connecting the GOT to a controller with reference to
the following manual.

Precautions for Wiring/Connecting the EMC Directive-Compliant Product
Wire and connect GOT1000 series equipments as instructed below. If the GOT1000 series equipments are configured in
a way different from the following instructions, the system may not comply with EMC directives.
Power and ground wires wiring method
(1) Power and ground wires wiring method
Connect the power wire and connection cable as shown in the illustration, and be sure to attach a ferrite core
(TDK Corporation type ZCAT3035-1330 or similar) within the range shown below.
Lead the power wire and ground wire as shown in 5.2.1 Control panel (2).
Be sure to ground the FG cable, and protective ground cable.
The cable need to be independently tested by the user to demonstrate EMC
compatibility when they are used with the GOT, the PLC of MELSEC-Q series,
MELSEC-L series, MELSEC-QnA, MELSEC-A series and MELSEC-FX series.
