Please follow the following safety attentions since they are intended to prevent
any possible accident and danger so that you can use this product safely and
correctly.
Safety attentions may classify into ‘Warning’ and ‘Caution’ and their meaning is
as following:
Symbol
Meaning
WARNING
This symbol indicates the possibility of death or
serious injury.
CAUTION
This symbol indicates the possibility of injury or
damage to property.
The meaning of each symbol in this manual and on your equipment is as follows.
Symbol
Meaning
This is the safety alert symbol.
Read and follow instructions carefully to avoid
dangerous situation.
This symbol alerts the user to the presence of
“dangerous voltage” inside the product that might
cause harm or electric shock.
After reading this manual, keep it in the place that the user always can contact.
This manual should be given to the person who actually uses the products and is
responsible for their maintenance.
WARNING
Do not remove the cover while power is applied or the unit is in
operation.
Otherwise, electric shock could occur.
Do not run the inverter with the front cover removed.
Otherwise, you may get an electric shock due to high voltage terminals or
charged capacitor exposure.
Do not remove the cover except for periodic inspections or wiring,
even if the input power is not applied.
Otherwise, you may access the charged circuits and get an electric shock.
Wiring and periodic inspections should be performed at least 10
minutes after disconnecting the input power and after checking the

WARNING
DC link voltage is discharged with a meter (below DC 30V).
Otherwise, you may get an electric shock.
Operate the switches with dry hands.
Otherwise, you may get an electric shock.
Do not use the cable when its insulating tube is damaged.
Otherwise, you may get an electric shock.
Do not subject the cables to scratches, excessive stress, heavy
loads or pinching.
Otherwise, you may get an electric shock.
CAUTION
Be cautious when handling CMOS elements on the option board.
It may cause a failure due to static electricity.
When changing and connecting communication signal lines,
proceed the work while the inverter is turned off.
It may cause a communication error or failure.
Make sure to connect the inverter body to the option board
connector accurately coincided each other.
It may cause a communication error or failure.
Make sure to check the parameter unit when setting parameters.
It may cause a communication error.

1. Introduction
Ethernet communication option module connects the iS7 inverter to the
Ethernet network. It supports 2 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 is possible. But, Ethernet network of the factory has to be
connected to Internet through Gateway.
With simple wiring, installation time can be reduced and maintenance
becomes easier.

(3) Mounting the communication option module on iS7 inverter
①Remove the cover of the iS7 inverter.
②iS7 communication option After connecting the EtherNET / IP communication
option to the connection part, tighten the screws (2 pieces).
③iS7 inverter and EtherNET / IP communication option have been concluded.
Do not install or remove the EtherNET / IP communication option while the
iS7 inverter is powered on.
Install or remove the EtherNET / IP communication option after the voltage of
the capacitor of the inverter is completely discharged.
Make sure that the inverter main unit and the option connector match exactly.

Modbus TCP is divided into Client and Server. The Client gives
command and the Server responses to the command. Generally,
Clients can be PLC, HMI, or PC and the Server is the inverter.
