SAFETY PRECAUTIONS
Always follow safety precautions to prevent accidents and potential hazards from occurring.
Safety precautions are classified into “WARNING” and “CAUTION” in this manual.
WARNING
Indicates a potentially hazardous situation which, if not avoided,
CAUTION
Indicates a potentially hazardous situation which, if not avoided,
can result in serious injury or death.
can result in minor to moderate injury, or serious damage to the
product.
Throughout this manual we use the following two illustrations to make you aware of safety
considerations:
Identifies potential hazards.
Read the message and follow the instructions carefully.
Identifies shock hazards.
Particular attention should be directed because dangerous voltage may be present.
Keep this manual at handy for quick reference.
CAUTION
Do not touch the CMOS components unless the board is grounded.
ESD can cause break down of CMOS components.
Do not change the communication cable with the inverter power is turned on.
Otherwise, there is a danger of connecting error and damage to the board.
Make sure to precisely insert the connector of inverter and option board
Otherwise, there is a danger of connecting error and damage to the board.
Check the parameter unit when setting the parameters.
Otherwise, there is a danger of connecting error and damage to the board.

Introduction
By using a MODBUS-RTU Option board, SINUS N inverter can be connected to a MODBUS-RTU
network.
Easy use of inverter operation, monitoring by User program and Parameter change and monitoring are
available using PC.
1.1 Interfacing type of RTU Reference
- Allows the drive to communicate with any makers’ computers.
- Allows connection of up to 16 drives by multi-drop link system.
- Ensure noise-resistant interface.
Users can use any kind of RS232-485 converters. However a converter that has built-in ‘automatic RTS
control’ is highly recommended. The specifications of converters depend on the manufacturers. Refer to the
converter manual for detailed converter specifications.
1.2 Before Installation
Before installation and operation, this manual should be read thoroughly. If not, it can cause personal injury
or damage other equipment.

Installation
4.1 Installation of Comm. board
①
Connect the option board to the inverter control board using each connector on the board (See the
Figure 2). Check for the position of supporter. Incorrect installation results in faulty connection of
option card.
②
Double check the board is firmly installed to the board and then apply the inverter power.
③
When card installation and parameter setting are finished, turn the power off to connect the
converter.
④
Connect the jumper for terminating resistor when option card is connected at the end of network.
(see figure 3).
⑤
When ①~④ is done correctly, set the parameters for communication according to the below table.

Note 1) It is used for Emergency Stop when communication between inverter and master is not done
properly. It is activated when communication is not made even once for the set time. It means
remote controlling of inverter is not done. Set this value for safety.
⑥ Turn off the inverter power before the connection of the Converter when parameter setting is
finished.

There are two holes on the option board for connection of option and inverter. Use left hole for models
SINUS N 0001/0002 and right for models SINUS N 0003/0005 series.
For models SINUS N 0003/0005 as shown above, loosen the bolt on the connector for Comm. Option
and tighten it onto the supporter on the inverter case. Before fixing the option board, bottom cover plastic
part for Comm. Option should be removed using knife or driver. The same method is used as 0001/0002
installation.
Connect the option board to inverter and reapply the bottom cover before tightening the supporter.
Follow the opposite order when dissembling.
