1. Introduction
1.1 What is Ethernet?
Ethernet communication module board connects the WD4X
inverter to the Ethernet network. It supports two kinds of
protocol, Modbus/TCP and Ethernet/IP.
Controlling and monitoring of inverter can be done by PLC
sequence program or any Master Module. Since Ethernet which
constitutes Internet has been used and IPv4 has been supported,
wherever Internet can be done, controlling and monitoring are
possible. But, Ethernet network of the factory has to be
connected to Internet through gateway.
Installation time can be reduced and maintenance becomes
easier just simple wiring.

2.3 Installation
Warning) Connect a communication network after the power supply
is off. If Ethernet communication module is removed or installed, the
power supply should be switched off. Otherwise, the WD4X inverter
will be damaged entirely. Take off Ethernet communication module
from the product after the power supply is totally discharged.
Step 1:
Loosen all cover screws and remove cover.
Step 2:
Remove the keypad connector.
Step 3:
Remove the keypad adapter PCB.
It may be helpful to use a screwdriver
to clear the plastic tabs.

Step 4:
Once the keypad PCB adapter is removed,
install the two standoffs which are included
in the Ethernet card kit.
Step 5:
Install the Ethernet card.
Step 6:
Install the two screws to secure the Ethernet
card to the standoffs. Snap the keypad adapter
PCB into place on top of the Ethernet card.
Step 7:
Reconnect keypad connector cable.
Connect network cable. Reinstall front cover.

2.6 Protocol Selection
For using the WD4X Ethernet option module, there are 2 kinds
of protocols, Modbus TCP and Ethernet IP. You can select one
of the protocols by selecting the No.1 switch. The switch is
placed next to the Ethernet connector for Ethernet cable. No. 2,
3 and 4 of switch are not available.
Switch State Protocol
OFF (Switch at the upper position) Modbus TCP
ON (Switch at the lower position Ethernet IP
If the option module is operating, protocol will not be changed
even if switch selection is changed. Protocol is determined by the
state of switch when the option module is turned on or the
inverter is initialized by ‘Yes’ execution of COM-94 Comm Update.
