Quick Installation Guide
“OPC-ETH” Multiprotocol Ethernet Interface Card
Thank you for purchasing the OPC-ETH Multiprotocol Ethernet Interface (herein after called the OPC-ETH card). This quick installation
guide has been prepared to help you connect your inverter to Modbus/TCP, EtherNet/IP, Allen Bradley CSP, and BACnet/IP networks.
Of the three option connection ports (A-, B-, and C-ports) provided on the inverter, the OPC-ETH card is mechanically keyed to
allow installation only onto the A-port. Once the inverter is equipped with this card, no other fieldbus cards (e.g., DeviceNet) are
allowed on the inverter. Mounting more than one fieldbus card onto the inverter will result in an
“Er4”
trip, which cannot be
reset until all cards but one are removed. Refer to section "6. Inverter Faults" for more information about the
“Er4
” trip.
1. Unpacking Confirmation
(1) Ensure that the OPC-ETH card and two M3x6
mounting screws are contained in the package.
(2) Ensure that the OPC-ETH card was not damaged
during transport (no broken components, dents or
warpage.)
(3) Ensure that the model name "OPC-ETH" is
printed on the OPC-ETH card (Figure 1).
If you suspect the device is not working properly or if
you have any questions about the device, please
contact the seller or your local Fuji representative.

2. Installation
Before starting installation and wiring, turn OFF the inverter’s power and wait at least 10 minutes. Additionally, ensure that the charge
lamp is turned OFF and confirm that the DC link bus voltage as measured between the P(+) and N(-) terminals is at a safe level (+25
VDC or less) using a multimeter or similar instrument.
Failure to follow this precaution may result in an electric shock.
(1) Remove the front cover from the inverter to expose the control printed circuit board (control PCB) (Figure 3).
To remove the front cover, refer to the Inverter Instruction Manual.
(2) Insert connector CN1 located on the back side of the OPC-ETH card (Figure 2) into the A-port (CN4) on the inverter control PCB.
Next, install and tighten the mounting screws that came with the OPC-ETH card (Figure 4).
Confirm that the positioning notch (Figure 1) is fitted on the tab (
in Figure 4) and connector CN1 is
fully inserted (
in Figure 4). Figure 5 shows the OPC-ETH card correctly mounted.
(3) Connect the network cables as necessary. Insert the Ethernet cables into the Ethernet jacks.
In general, the insulation for control signal wires is not specifically designed to withstand high voltages (i.e. reinforced insulation is not
applied). Therefore, if a control signal wire comes into direct contact with a live conductor, the insulation may prematurely fail and
expose the signal wire to high voltages. Ensure that the control signal wires will not come into contact with live conductors.
Failure to follow this precaution may result in an electric shock.
Electrical noise may be emitted from the inverter, motor and wires. Take appropriate measures to prevent nearby sensors and similar
devices from malfunctioning due to ambient electrical noise.
Failure to follow this precaution may result in device malfunction.

6. Inverter Faults
Option communication error (Er4)
A communication error has occurred between the OPC-ETH card and the inverter.
Possible Causes
What to Check and Suggested Remedies
(1) There is a problem with the
connection between the OPC-ETH
card and the inverter
Check if the OPC-ETH card connector is firmly engaged with the inverter control board
connector
Reinstall the OPC-ETH card on the inverter
(2) Strong electrical noise
Check if appropriate noise control measures have been implemented (e.g. correct
grounding and routing of signal wires, communications cables, and main circuit wires)
Implement noise control measures
(3) Another fieldbus option card is
mounted on the inverter with the
OPC-ETH card
Check if other fieldbus cards (DeviceNet, etc.) are mounted on any other inverter control
board option ports (B-port and C-port)
Remove all other fieldbus cards except for the OPC-ETH
Option error (Er5)
An internal error has occurred on the OPC-ETH card.
Possible Causes
What to Check and Suggested Remedies
(1) A network communications timeout
has occurred
Check if a network connection has timed out (also refer to Table 2 above)
Re-establish the network connection
(2) An internal error has occurred on
the OPC-ETH card
Check if this error is due to the OPC-ETH card itself
The CPU or the printed circuit board (PCB) may be defective or damaged: contact your
Fuji Electric representative for further assistance
