Removal of the Ethernet board

The Ethernet board is installed in the initial status. Before wiring cables to the control circuit terminals
or to the main circuit terminals on the FR-E740-170SC or lower or FR-E720S-050SC or lower inverter,
remove the Ethernet board as follows.
Fig. 3-28: Components of the Ethernet board
Remove the inverter front cover. (Refer to fig. 2-7 to remove the front cover.)
Remove the three mounting screws to remove the Ethernet board, Ethernet board spacer, junc-
tion connector, and hexagon spacer.
NOTES After the installation of the inverter or the wiring of the cables to the main or control circuit termi-
nals, ensure to reinstall the Ethernet board to the inverter in the reverse order. The tightening
torque for the mounting screws of the Ethernet board is 0.2 to 0.4 Nm.
Plug-in options cannot be used with this inverter.
Earthing (grounding) for Ethernet board
To reduce noise of the Ethernet cable, connect an earth (ground) cable from the lower left M3 mount-
ing screw on the Ethernet board to the inverter enclosure (the earth cable must be as short as
possible).
