Connecting The Display Unit With Ethernet - Mitsubishi Electric MELDAS C6 Maintenance Manual

4.12 Connecting the Display Unit with Ethernet

To connect the display unit with Ethernet, the Ethernet card (FCU6-EX875) must be mounted to the
extension slot EXT2 on the control unit.
Connect the Ethernet cable to the modular jack on the Ethernet card.
As the Ethernet cable is easily affected by noise, separate the drive line and power line, and install the
enclosed ferrite core on the control unit side.
When using in an adverse environment, or when compliance to EMC Directives is required, use a
shielded cable.
Refer to the instruction manual for the display to be connected for details on other precautions.

(Note 1) Install the ferrite core with the following procedure.
(1) Wind the cable once.
(2) Securely insert the case until a click is heard.
(3) Fix with constraining bands so that the position does not
(Note 2) When using a shielded cable, a separate FG cable is required for
connecting the shield to the FG.
Normally, the cable is connected to the FG terminal on the control
unit. However, if the ground plate is closer, connect the cable
directly.
(Note 3) To comply with the EMC Directives, a ferrite core may also need to
be installed on the display side.
